[Chemical Knowledge]:What are the upstream raw materials for thioglycolic acid? What do the downstream products contain?

Thioglycolic acid (TGA) is a kind of organic acid containing thiol (-SH) functional group, which is widely used in chemical industry, medicine, agriculture and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of thioglycolic acid mainly include the following categories:

1. Upstream product

(1) Acetaldehyde: Acetaldehyde reacts with hydrocyanic acid to generate acetaldehyde nitrile, which can be hydrolyzed to obtain thioglycolic acid.

(2) Sulfuric acid: Sulfuric acid is used as a catalyst in the production of thioglycolic acid to promote the reaction.

(3) hydrocyanic acid: hydrocyanic acid reacts with acetaldehyde to form acetaldehyde nitrile, which is hydrolyzed to give thioglycolic acid.

2. Downstream products

(1) Ethyl mercaptoacetate: thioglycolic acid and ethanol esterification reaction to generate ethyl mercaptoacetate, is an important pharmaceutical intermediates.

(2)N-phenylglycine: Mercaptoacetic acid reacts with aniline to produce N-phenylglycine, which is a pesticide intermediate.

(3) dithiodipropionic acid: thioglycolic acid reacts with sulfuric acid to generate dithiodipropionic acid, which is a rubber additive.

(4) thioglycolate isooctyl: thioglycolic acid and isooctyl alcohol react to generate thioglycolate isooctyl, is a plastic stabilizer.

above is only part of the upstream and downstream related products of thioglycolic acid. In fact, thioglycolic acid has a wide range of applications in the chemical industry, and there are many upstream and downstream products. The specific products are related to the production process, raw material sources, market demand and other factors.
