Method B.-Monoisobutyrate, monostearate, diacetate, diisobutyrate, dicaproate, distearate, and dibenzoate: The reaction vessel was a three-necked flask fitted with a thermometer, dropping funnel, and mercury-sealed stirrer. For monoester formation, 0.50 mole of the acid chloride was added dropwise, over a period of one hour at a reaction temperature of 25-35", to a stirred, cooled mixture of 0.50 mole of 2-methyl-2, 4-pentanediol (10% excess for the ...
