| titleOfInvention | Improvements in and relating to the production of esters |
| abstract | Esters are prepared by reacting a compound R.CH = CH.CH(R1)X in which R is hydrogen or alkyl, R1 is hydrogen or alkyl and X is chloride or acyloxy, with a solution containing a carboxylic acid, a palladous salt, a cupric salt, a metal halide, other than a fluoride, and less than 25% by weight of water. Molecular oxygen, e.g. as air, may be passed through the reaction mixture to regenerate the catalyst. Allyl acetate, which gives glyceryl esters, particularly di- and tri-acetates when acetic acid is used, allyl chloride which gives mono- and di-acetates of 1:2 - dihydroxy - 3 - chloropropane, crotylacetate, and 3-acyl-oxybut-1-ene which give di- and tri-acetates of n-butane-1 : 2 : 3-triol, and crotyl chloride which gives mono- and diacetates of 2 : 3-dihydroxy - 1 - chlorobutane are mentioned. A metal carboxylate, e.g. of lithium or copper corresponding to the free carboxylic acid used may be included in the reaction mixture to reduce any induction period. By-products may be formed, e.g. when allyl acetate is used in addition to glyceryl acetates, diacetates of 1 : 2-di-hydroxy-3-chloropropane and 1 : 3 - dihydroxy - 2 - chloropropane are formed and glycerol is formed by hydrolysis of the mixture. Other by-products are the acetate of hydroxy-acetone, acrolein, and a -, b - and g -acetoxy allyl acetate. Examples describe the preparation of glyceryl di- and tri-acetates. |
