Abstract

The invention comprises esters of the general formula: <FORM:0963902/C1/1> where the symbol R represents a hydrocarbon radical and n represents a number from 1 to 40 and the preparation thereof by heating a semi-ester of the general formula: <FORM:0963902/C1/2> where the symbol R has the meaning defined above, with ethylene oxide in the presence of an oxyethylation catalyst and in the absence of oxygen. The oxyethylation catalyst may be an alkaline substance e.g. a lithium, sodium or potassium, hydroxide carbonate or alcoholate containing an alkyl group having 1 to 6 carbon atoms preferably a lithium, sodium or potassium salt of the semi-ester starting materials, when the reaction is carried out in the temperature range of 100 DEG to 200 DEG C. to give a product of the formula I when the symbol n has the value 1. About 0.1% to 7%, preferably 0.1% to 2% of the semi-ester, calculated as the weight of alkali metal on the weight of semi-ester, may be used. The oxyethylation catalyst may also be a Lewis Acid, e.g. an aluminium halide, phosphorus pentafluoride or a complex compound thereof, titanium tetrachloride, tin tetrachloride, ferric chloride or zinc chloride, when the reaction is carried out at 30 DEG to 100 DEG C. to give a compound of the formula I where the symbol n has the values 2 to 40, 0.1% to 7% by weight, calculated on the semi-ester of the formula II, of the Lewis Acid may be used.ALSO:The invention comprises mixed esters of the general formula: <FORM:0963902/C3/1> where the symbol R represents a hydrocarbon radical and the symbol n is 1 to 40 and the preparation thereof by heating a semi-ester of the general formula: <FORM:0963902/C3/2> when the symbol R has the meaning defined above with ethylene oxide in the presence of an oxyethylation catalyst. The oxyethylation-catalyst may be a Lewis acid e.g. an aluminium halide, phosphorus pentachloride or a complex compound thereof, titanium tetrachloride, tin tetrachloride, ferric chloride or zinc chloride, when the reaction is carried out at 30 DEG to 100 DEG C to give a compound of the formula I where the symbol n has the values 2 to 40. 0.1% to 7% by weight calculated on the weight of semi-ester of the formula II, of the Lewis acid may be used.
