Abstract

Prods. ROOC-(CH2)n-X-(CH2)m-COOR (I) are prepd. by reacting a dinitrile NC-(CH2)n-X-(CH2)m-CN (II) with an alcohol R-OH (III). In the formulae, R stands for alkyl with 8-18 carbons, the two R gps. in formula (I) may be identical or different, X is oxygen, sulphur or methylene, m and n are independently 1, 2 or 3. - Reaction is carried out in the presence of 0.025-0.1 mole of an alcohol with 1-6 carbons, of 1.3-3.0 mole sulphuric-acid and 4-15 mole water for 1 mole of dinitrile of general formula (II).
