Catalytic systems containing Te02, HBr and AcOH have been used industrially by Oxirane to convert ethylene to ethylene glycol via the formation of mono- and di-acetate (equations 131 and 132).359-361 The overall yield from ethylene to ethylene glycol is more than 90%, making this reaction competitive with respect to the older silver-catalyzed ethylene epoxidation process. 

The cyclohexane-1,2-di acetal group can be introduced by transketal-isation with 1,1,2,2-tetramethoxycyclohexane. The Dispoke and CDA group can be removed by transketalisation with ethylene glycol in the... 

Scheme 7.38 Free radical copolymerization of various alicyclic monomers initiated by (1) azoisobutyronitrile (AIBN) in THF, and (2) di-tert-butyl peroxide (DTBP) in propylene glycol monomethylether acetate, and used in the synthesis of the alicyclic polymer resist materials for ArF lithography, pioneered at the University of Texas at Austin in 1995. Note that although only 2,3-enchainment of the cyclic olefins is shown above the scheme, 2,7-enchainement is also possible, as reported by Gaylord and co-workers. ...

Plasticisers are also used in products such as lacquers and adhesives that fall outside the definition of the plastics industry. Dicyclohexyl phthalate is used in nitrocellulose lacquers polyethylene glycol and its monostearate are compatible with cellulose nitrate. Dibutyl maleate is compatible with polyvinyl acetate, and di- -hexyl adipate, diethylene glycol di-2-ethyl butyrate or dibutyl sebacate can be used in polyvinyl butyral. Benzoates are recommended for... 

Triethylene Glycol Di(2-ethylhexanoate) n (-CH2O CH2CH200C-C7Hi5)2. a plasticizer for cellulosic plastics, polymethyl methacrylate, PVC, and vinyl chloride-vinyl acetate copolymers. In vinyls it is usually used as a secondary plasticizer at 10-25% of the total plasticizer, to impart low-temperature flexibility. 

Chlorotoluene [95-49-8] (l-chloto-2-methylben2ene, OCT) is a mobile, colorless Hquid with a penetrating odor similar to chlorobenzene. It is miscible ia all proportions with many organic Hquids such as aUphatic and aromatic hydrocarbons, chlorinated solvents, lower alcohols, ketones, glacial acetic acid, and di- -butylamine it is iasoluble ia water, ethylene and diethylene glycols, and triethanolamine. 

Plasticizers. Plasticizers are materials that soften and flexibilize inherently rigid, and even britde polymers. Organic esters are widely used as plasticizers in polymers (97,98). These esters include the benzoats, phthalates, terephthalates, and trimeUitates, and aUphatic dibasic acid esters. Eor example, triethylene glycol bis(2-ethylbutyrate) [95-08-9] is a plasticizer for poly(vinyl butyral) [63148-65-2] which is used in laminated safety glass (see Vinyl POLYMERS, poly(vinyl acetals)). Di(2-ethyUiexyl)phthalate [117-81-7] (DOP) is a preeminent plasticizer. Variation of acid and/or alcohol component(s) modifies the efficacy of the resultant ester as a plasticizer. In phthalate plasticizers, molecular sizes of the alcohol moiety can be varied from methyl to tridecyl to control permanence, compatibiUty, and efficiency branched (eg, 2-ethylhexyl, isodecyl) for rapid absorption and fusion linear (C6—Cll) for low temperature flexibiUty and low volatility and aromatic (benzyl) for solvating. Terephthalates are recognized for their migration resistance, and trimeUitates for their low volatility in plasticizer appHcations. 

Di-(/)-chlorophenyl)-acetic acid has been made by the action of alcoholic potassium hydroxide on l,l-di-(/>-chlorophenyl)-2,2-dichloroethane by the action of barium hydroxide on DDT in ethylene glycol and by the condensation of chlorobenzene with glyoxylic acid. ... 

A mixture of 1.0 g of 6,6,9-trimethyl-9-azabicyclo[3.3.1 ] nonan-3/3-ol, methyl 0i,0i-di-(2-thienyD-glycollate and 30 mg of metallic sodium is heated at 80°C to 90°C for about 2 hours under reduced pressure. After cooling, ether is added to the reaction mixture. The mixture is extracted with 10% hydrochloric acid. The aqueous layer is alkalified with sodium carbonate and reextracted with ethyl acetate. The extract is washed with water, dried and concentrated to dryness. The residue thus obtained is treated with hydrogen chloride by conventional manner. 2.0 g of the 0i,0i-di-(2-thienyl)glycollate of 6,6,9-trimethyl-9-azabicyclo-(3.3.1 ] nonan-3/3-ol hydrochloride are obtained. Yield 83%. 

Ketene di(2-melhoxyethyl) acetal has been obtained by the present method with the use of diethylene glycol dimethyl ether as solvent.3 Other methods for the preparation of ketene acetals include the dehydrohalogenation of a halo acetal with potassium t-butoxide 4 and the reaction of an a-bromo orthoester with metallic sodium.5...

The solvents most commonly employed are water, ethyl and methyl alcohol, ether, benzene, petroleum ether, acetone, glacial acetic acid also two or three solvents may be mixed to get the desired effect as described later. If you still cannot dissolve the compound, try some of these chloroform, carbon disulfide, carbon tetrachloride, ethyl acetate, pyridine, hydrochloric acid, sulfuric acid (acids are usually diluted first), nitrobenzene, aniline, phenol, dioxan, ethylene dichloride, di, tri, tetrachloroethylene, tetrachloroethane, dichloroethyl ether, cyclohexane, cyclohexanol, tetralin, decalin, triacetin, ethylene glycol and its esters and ethers, butyl alcohol, diacetone alcohol, ethyl lactate, isopropyl ether, etc.
