ABSTRACT:
The dimethyl ethers of succinic, glutaric and adipic acids show a great increase in their water miscibility when they are mixed with either 6-hydroxycaproic acid methyl ester, one or more of the glycol ethers, diglycol ethers and glycol ether acetates, or both 6-hydroxycaproic acid methyl ester and one or more of the glycol ethers, diglycol ethers and glycol ether acetates. These dimethyl esters are, accordingly, substituents for the glycol ether derivatives in water-miscible solvents for film-forming resins. They may provide up to 80% by weight of the non-water components of the solvent. They may be produced at the same time as the methyl ester of 6-hydroxycaproic acid in a single esterification step by esterifying a fraction of acids derived from the waste salt solutions of cyclohexanone manufacture, as described in a related application, Ser. No. 372,021, now U.S. Pat. No. 3,859,335.
