Solvent, solvents aliphatic hydrocarbon

The semicrystalline polyesters of the terephthalate and naphthalate family are resistant to a wide range of chemicals at room temperature, including water, alcohols, ketones, ethers, glycols, chlorinated solvents, aliphatic hydrocarbons, and oils. They are slowly hydrolyzed in boiling water and rapidly degraded in strongly basic or acidic medium.

The synthesis, which at room temperature may require days, or even weeks, needs an alkylated phenol, hydroquinone, copper stearate or other polymerization inhibitor, but often the use of elevated temperatures and appropriate solvents (aliphatic hydrocarbons, CH2C12) allows a more rapid cycloaddition. 

The purple crystals are freely soluble in all common organic solvents except aliphatic hydrocarbons, in which they are only sparingly soluble. Solutions of the compound are highly sensitive to oxidation, and rigorous exclusion of air is necessary. The appearance of yellow material, insoluble in hydrocarbons, indicates the onset of oxidation. The purple solid is pyrophoric in air but is stable indefinitely when stored under an inert atmosphere at room temperature.

Properties Colorless (when pure), tacky hquid. D 1.05, refr index 1.47, solidifies near 0C. Soluble in water at 32C above which it precipitates from water but redissolves on cooling. Soluble in most organic solvents except aliphatic hydrocarbons. Compatible with rubber latexes, rosin derivatives, and some phenolics. Combustible. 

Properties Water-white to amber liquid depending on purity hygroscopic. D 1.20, refr index 1.420, bp (pure compound) 135-138C (1 mm Hg). Miscible with water and all organic solvents except aliphatic hydrocarbons hydrolyzed in water with formation of mono-, di-, and triethyl orthophosphates water solutions attack metals commercial material contains 40% TEPP.

Behaves like a hydrocarbon solvent. An excellent solvent for aliphatic hydrocarbons with an estimated 20 carbons or less and for most aromatic hydrocarbons. Cosolvents, such as methanol and acetone, enhance the solubility of polar solutes in COj. Organic solvents, such as halocarbons, aldehydes, esters, ketones, and alcohols, are freely soluble in supercritical COj. 

PPO has excellent resistance to most aqueous reagents and is unaffected by acids, alkalis, and detergents. The polymer has outstanding hydrolytic stability and has one of the lowest water absorption rates among the engineering thermoplastics. PPO is soluble in aromatic hydrocarbons and chlorinate solvents. Several aliphatic hydrocarbons cause environmental stress cracking. 

Tetrahydrofurfuryl alcohol [97-99-4] is a colorless liquid with a weak odor that is miscible with water and organic solvents except aliphatic hydrocarbons. It dissolves cellulose nitrate and acetate, chlorinated rubber, shellac, resin esters, and many other binders. 

Diacetone alcohol [123-42-2] (4-hydroxy-4-methyl-2-pentanone) is an almost odorless ketone alcohol that is weakly acidic as a result of rearrangement to the enol form. It is miscible with water and organic solvents except aliphatic hydrocarbons. It acts as a good solvent for cellulose esters and ethers, alcohol-soluble resins, castor oil, and plasticizers. Poly(vinyl acetate) and chlorinated rubber are partially dissolved or swollen. Polystyrene, poly(vinyl chloride), vinyl chloride copolymers, dam-ar resins, resin esters, rubber, bitumen, mineral oils, ketone resins, and maleate resins are insoluble. Diacetone alcohol is used as a high boiler in stoving enamels to improve flow and gloss. 

Methyl glycol [109-86-4] (2-methoxyethanol, ethylene glycol monomethyl ether) has a slight odor, and is miscible with water and organic solvents except aliphatic hydrocarbons. It is a very good solvent for many natural and synthetic resins. It does not dissolve fats, oils (except castor oil), damar resin, rubber, bitumen, hydrocarbon resins, polystyrene, poly(vinyl chloride), and vinyl chloride copolymers. On account of its teratogenic properties it is replaced as a solvent in the paint and colorants sector by other solvents or solvent mixtures. 

N.N-Dimethylformamide [68-12-2] (DMF) [14.276] is miscible with water and organic solvents except aliphatic hydrocarbons. It is a good high-boiling solvent for cellulose esters, cellulose ethers, poly(vinyl chloride), vinyl chloride copolymers, poly(vinyl acetate), polyacrylonitrile, polystyrene, chlorinated rubber, polyacrylates, ketone resins, and phenolic resins. Alkyd resins and resin esters are partially soluble. Dimethylformamide does not dissolve polyethylene, polypropylene, urea-formaldehyde resins, rubber, and polyamides. It is used as a solvent in printing inks, for polyacrylonitrile spinning solutions [14.277], and as a solvent in the synthesis of acetylene. 

Procedure consisted of 3 equal volume extractions with 35 vol. % reagent in Gulf BT Solvent (aliphatic hydrocarbon) from 8 M HNO3 solution (except primary amine extraction in which 6 M HNO3 was used). T ie secondary, tertiary, and quaternary amines had 10 vol. % decyl alcohol. The solutions were stripped - th 3-1/3 volume portions of 0.1 M hydroji lamine nitrate.
