Inventors:

Eugene G. Harris - West Chester OH

Assignee:

National Distillers and Chemical Corporation - New York NY

International Classification:

C07C 4134
C07C 4103

US Classification:

568648

Abstract:

Ethylene glycol monoaryl ethers useful as fragrance chemicals are obtained by ethoxylating a phenol in the presence of an alkali metal borohydride and alkali metal hydroxide and neutralizing the resulting monoethoxylated product to pH 6. 5-7. 5 with an aliphatic di- or polycarboxylic acid or hydroxyaliphatic carboxylic acid. Ethylene glycol monophenyl ether having a consistent mild rose odor profile and free of undesirable metallic notes is obtained by the present process.

International Classification:

C07D30702

US Classification:

549484

Abstract:

2,3-Dihydrofurans having highly desirable odor characteristics closely mimicking that of natural products are provided herein. The 2,3-dihydrofurans correspond to the formula ##STR1## wherein R' is an alkyl group having from 1 to 4 carbon atoms, R** is an alkyl group having from 1 to 5 carbon atoms, R. sub. 1 is an alkyl group having from 1 to 4 carbon atoms, R. sub. 2 is hydrogen or an alkyl group having from 1 to 6 carbon atoms, and R. sub. 3 and R. sub. 4 are hydrogen or a methyl group. The 2,3-dihydrofuran compounds are useful in the preparation of fragrance compositions and fragranced articles and can be employed in conjunction with known fragrance materials to augment or enhance the aromas thereof.

Abstract:

A process is provided for the continuous or semi-continuous production of hetero-macrocyclic compounds including lactones and cyclic esters. The process involves the catalyzed depolymerization of linear polyesters at elevated temperature and under reduced pressure in the presence of a specified amount of monocarboxylate moieties while providing top-to-bottom mixing throughout essentially the total volume of the reaction mass.
