Solvents safety

The solvent industry has made significant strides in developing newer grades and blends of solvents for a variety of applications. Safety solvents are being developed that are low in volatility (vapor pressure), low in toxicity, and biodegradable. However, these newer solvents are finding commercial acceptance mainly as cleaning solvents rather than as a dilution medium for epoxy resins. For adhesives, rather than replace the solvent, the trend has been to develop waterborne emulsions. 

Stoddard solvent is a colorless, flammable liquid that smells and tastes like kerosene. It will turn into a vapor at temperatures of 150 to 200 °C. Stoddard solvent is a petroleum mixture that is also known as dry cleaning safety solvent, petroleum solvent, and varnoline its registered trade names are Texsolve S and Varsol 1 . It is a chemical mixture that is similar to white spirits. Stoddard solvent is used as paint thinner in some types of photocopier toners, printing inks, and adhesives as a dry cleaning solvent and as a general cleaner and degreaser.

Safety. Solvents with low potential for fire and reactive chemistry hazards are preferred as inherently safe solvents. In all cases, solvents must be used with a full awareness of potential hazards and in a manner consistent with measures needed to avoid hazards. For information on the safe use of solvents and their potential hazards, see Sec. 23, Safety and Handling of Hazardous Materials.

NAPHTHA SAFETY SOLVENT (8052-41-3) Forms explosive mixture with air (flash point 100°-140°F/38°-60°C). Incompatible with nitric acid, strong oxidizers. Attacks some plastics, rubber, and coatings. Flow or agitation of substance may generate electrostatic charges due to low conductivity.

The cyclic trimer ketone peroxides (eg, methyl ethyl ketone peroxide cyclic trimer [24748-23-0]) have been selectively prepared in dilute solution (in a safety solvent due to the shock sensitivity of the pure peroxide) for use as impromoted, thermal initiators (124,125). They have been shown to effectively modify polyolefins under certain conditions in a manner similar to dialkyl peroxides.

These are liquids which dissolve other substances. They can be more or less pme organic chemical compounds or mixtures. They can be synthetic or if not natural, obtained from natural somees for example, mar r of the oil refinery cuts sold as industrial solvents are mixtures of organic chemical compoimds which are distilled from petroleum or distilled from it after cracking (chemical conversion). Matty are flammable, but synthetic compoimds where atoms of chlorine or fluorine are built-in (so-called safety solvents) may be non-flammable. The substance 1,1,1 - trichloroethane used in fabric protector sprays and fat-dissolving drain cleaners, is not flammable. However, beware of the words safety solvent . The solvents with chlorine in them, and to a lesser extent fluorine, still pose toxicity hazards, or a hazard to the ozone layer. Some classes of organic solvents are shown in Table 9.1. 

Substitution Where feasible, less toxic solvents should be substituted for highly toxic solvents. As discussed earlier, aqueous systems are the least toxic and are nonflammable. Water with safe additives may be effective however, if water has insufficient solvent power, safety solvents, such as aliphatic hydrocarbons and fluorinated hydrocarbons should be considered before the more toxic solvents, such as toluene, ethylene dichloride, and trichloroethylene. When the more toxic solvents must be used, control measures such as local exhaust ventilation systems should be employed to remove volatile vapors and mists at the source. A review system should be in place to identify highly toxic solvents such as benzene, carbon tetrachloride, and gasoline and to ensure that appropriate substitutions are considered and/or controls are in place to address potential hazards. 

Cleaning fluids should be clearly labeled, capped, and stored in a cool, well-ventilated place away from sparks and flames. Typical cleaning fluids are kerosene and various safety solvents.
