SU105355A1 - The method of obtaining the thiol esters of formic acid - Google Patents

Description

And sb

Thiol esters of formic acid are obtained with a yield of up to 50%, they are easily acotalized when interacting with mercaptan in a stream of chloro etho1o of hydrogen, yielding Y (leera - d-rithiomuramic acid).

Example 1. Benzylthiol formate. A mixture of 10 wt. including beisylmercapta and 14.2 wt. Part of the sulphate ion mrid and monohydric acid and acetic acid are left for two days at room temperature, then heated to 45-ZO for two. After fractionated hieregoics, benzmltnolformate is obtained in a yield of 50% of the theoretical. Boiling point 124-124.5 with 19 mm p, -1.5768,

c / - -1.1304. Colorless, transparent liquid with zaiah, which is known as ayzylmercaptai.

Example 2. Ethylthiol formate.

They laugh at 17.1 wt. h. ethyld {yerkaitana e 49.5 ve. part of the formic and ukeusic xylate sulfide aehydride, and the reaction was carried out as described in Example 1. After the formation of the reaction, the reaction products are cooled. distillation Ethylthiol formate yield 35% of theoretical. Boiling point 100-101.5 at 753 mm. H., 4681; , 0238. Colorless, irazrachial liquid with smell, remind 1, it is ethyl mercaptai.

Subject invention

A process for the preparation of thiol esters of formic acid, characterized in that the pa mercaptans act with a mixture of acetic anhydride and acetic acids.
