Thiol sorbate
In organic chemistry, a thiol , or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group or a sulfhydryl group, or a sulfanyl group. Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl (−OH) group of an alcohol), and the word is a blend of "thio-" with "alcohol". WebThe thiol compounds react thermal addition reaction, radica l addition reaction, etc. to double bond competitively. With this characteristic, it can be used as a chain transfer agent at UV curing system and as a monomer at a thiol-en reaction. However, such biggest problem of a thiol compound is the instability (short pot life) in the
