Paint thinner

White-spirits are solvents that are slightly heavier than SBP s and have boiling ranges between 135 and 205°C. A dearomatized grade exists. These solvents are used essentially as paint thinners although their low aromatic content makes them unsuitable for lacquers, cellulosic paints and resins. 

Chlorotoluene isomer mixtures, especially those containing a relatively high amount of o-chlorotoluene, are widely used as solvents in industry for such purposes as metal-cleaning formulations, railroad industrial cleaners, diesel fuel additives, carbon removal procedures, paint thinners, and agricultural chemicals. Halso 99 andHalso 125 are examples of such solvents.

Several components of the organic phase contribute greatly to the character of the final product. The pore size of the gel is chiefly determined by the amount and type of the nonsolvent used. Dodecane, dodecanol, isoamyl alcohol, and odorless paint thinner have all been used successfully as nonsolvents for the polymerization of a GPC/SEC gel. Surfactants are also very important because they balance the surface tension and interfacial tension of the monomer droplets. They allow the initiator molecules to diffuse in and out of the droplets. For this reason a small amount of surfactant is crucial. Normally the amount of surfactant in the formula should be from 0.1 to 1.0 weight percent of the monomers, as large amounts tend to emulsify and produce particles less than 1 yam in size. 

The nurse must not give an emetic when a corrosive substance (such as lye) or a petroleum distillate (paint thinner, kerosene) has been ingested. In many cases of poisoning, it is preferable to insert a nasogastric tube to empty stomach contents. Emetics are used with great caution, if at all, when the substance ingested is unknown or in question. An emetic is never given to a patient who is unconscious or semiconscious because aspiration of vomitus may occur. 

Volatile solvents are fluids or gases contained in a wide variety of products (e.g., gasoline, paint thinner, butane gas) that have significant concentrations of aliphatic, aromatic, or halogenated hydrocarbons, which vaporize at room temperature. Because of their rapid absorption in the lungs, volatile solvents exert a rapid intoxicating effect.

Individuals who have had previous exposure to materials that chap or dry the skin, such as alcohols, gasoline, or paint thinners, may be more susceptible to percutaneous penetration of liquid agents. In these situations, the rate of percutaneous penetration of the agent is greatly increased resulting in a decrease in the survival time that would otherwise be expected. 

I started painting about 1980. We did a lot of architectural finishes, finishes with cyanide in them, things like that. Sometimes we burned old paint to remove it. When you burn paint it changes the composition. Not even the manufacturer can tell you what the composition will be once you heat it. We used paint thinner to get oil-based paint off our skin. That just zaps into the bloodstream. 

The SVE case history discussed is included as a typical situation, similar to many projects encountered in the field that diverge from the ideal case. The site is located adjacent to a vehicle maintenance building in southern California. A 3000-gal and a 5000-gal UST were used to store unleaded gasoline, and a 550-gal UST was used to store petroleum-based paint thinner (Figure 10.15). To add to the situation, different phases of the project were completed by different consultants, and, due to administrative issues, almost 4 years passed between removal of the USTs and completion of the remediation activities. 

Stoddard solvent is a petroleum distillate widely used as a dry-cleaning solvent and as a general cleaner and degreaser. It may also be used as paint thinner, as a solvent in some types of photocopier toners, in some types of printing inks, and in some adhesives. Stoddard solvent is considered to be a form of mineral spirits, white spirits, and naphtha however, not all forms of mineral spirits, white spirits, and naphtha are considered to be Stoddard solvent. 

There are certain compounds that have the remarkable characteristic of being able to selectively dissolve some compounds, while at the same time ignoring others. A familiar example might be to take a spoonful of table salt and drop it into a half a glass of paint thinner. The salt sinks to the bottom of the glass. Mix it, shake it, and it still settles down to the bottom because it wont dissolve in paint thinner. Having observed that, it would be tough to get that salt completely separated from the paint thinner. 

Now add a half a glass of water and stir. The salt disappears as it dissolves in the water. Now all you have to do is to separate the paint thinner and water by carefully pouring off the paint thinner, which has floated on the top. Then you just need to let the water stand for a couple of days and evaporate. In the bottom of the glass youVe got nearly all the salt you started with. 

Solvent extraction of benzene works the same way. But instead of water, the various solvents used are sulfolane, liquid SO2, diethylene-glycol, and NMP (N-methyl pyrrolidone). The paint thinner/salt/water process described above might be called a batch solvent process, since it consists of sequential steps that can be repeated, batch after batch. Some low-volume commercial processes still operate that way. 

Substance-Induced Dementias. Substances of abuse can also cause dementia. The most common is alcohol-related dementia. Chronic alcoholism leads to dementia in several ways. The poor diet of the alcoholic causes a deficiency of certain essential nutrients such as thiamine. The alcoholic often suffers recurrent head injuries from falls or altercations. Alcohol-induced liver failure can expose the brain to toxic injury. Finally, the direct toxic effects of alcohol itself on the brain can lead to dementia. In addition to alcohol, the abuse of inhalants such as paint thinner and... 

Strong acids include battery acid, murintic acid, and hydrochloric acid. Weak acids include acetic acid, toilet bowl cleaner, and lactic acid. Banned pesticides include Silvex, Mirex, Aldrin, Chlordane, DDT, and Heptachlor. Caustics include oven cleaner and drain cleaner. Flammables include alcohol, acetone, turpentine, lacquer, and paint thinner. Pesticides include rodent poisons, insecticides, weed killer, and other herbicides and fungicides. Pesticide containers should be triple-rinsed, and the contents sprayed on crops or yard, before discarding. 

Hexanone, also known as methyl n-butyl ketone or MBK, is a clear, colorless liquid with a somewhat sharp odor. The liquid form can easily evaporate into the air as a vapor. It is a waste product of wood pulping, coal gasification, and oil shale operations. 2-Hexanone was formerly used in paint and paint thinner and in various chemical substances. However, since it was found to have harmful health effects, it is no longer made in the United States, and its uses have been restricted. There are no known major natural sources of 2-hexanone in the environment. When 2-hexanone is released to rivers or lakes, it dissolves very easily, and it may evaporate into the air in a few days. We do not know if 2-hexanone binds to soil. When 2-hexanone is released to the water, air, or soil, it is probably broken down into smaller products, possibly within a few days. 

Turpentine is a mixture of CioHie volatile terpenes (hydrocarbons made of isoprene units). There are actually four different types and methods of making turpentine, including steam distillation of wood. The two pinenes, a and P, are major components of turpentine. Other compounds found in abundant amounts are camphene, dipentene, terpinolene, and A -carene. Although it has been replaced by petroleum hydrocarbons as paint thinners (lower price, less odor), turpentine is still a good solvent and thinner in many specialty applications. The use pattern for turpentine is as follows synthetic...

LEADX is a chemical additive that was developed to treat material contaminated with lead or other heavy metals in situ. LEADX may be added directly to soil or incorporated into sandblasting materials or paint thinners. LEADX penetrates the contaminated material and chemically bonds with heavy-metal contaminant to form an insoluble, nonleachable compound. The vendor claims that once bonded, the lead cannot be absorbed by plants or animals and is chemically rendered immobile. According to the vendor, it has been used in the following applications for the treatment of lead ... 

Micro-Flo has been used at many sites throughout Canada to treat wastewater and surface water contaminated with polychlorinated biphenyls (PCBs), chlorophenols, polycyclic aromatic hydrocarbons (PAHs), phenols, dioxins, furans, hydrocarbons, metals, oil, and grease. The technology has also been used to treat water contaminated with paint, paint thinner, and paint solvents. 

Inhalants are found in many commercial products and are not listed as controlled substances. They can be solvents such as toluene, found in paint thinner, degreaser, nail polish remover, gasoline, and glue propellants such as butane and propane. 

Following the lead provided in 1942 and thereafter by truck gardeners in carrot (S) and parsnip (ff) fields, investigations were started in nursery weed control, involving use of some of the more highly refined petroleum products known as mineral spirits or petroleum spirits. Their common industrial uses are as cleaning naphthas, paint thinners, and solvents. Among trade names of products successfully used in weed control in forest nurseries are Stoddard solvent, Sovasol No. 5, Varsol, Stanisol, Shell solvent, and Sohio weed killer.
