Abstract
The present invention relates to a process for producing an alkenyl mercaptan (2), comprising reacting an alkenyl halide (1) with an alkali hydrosulfide, wherein the reaction is carried out in the presence of a disulfide (3) in an amount of 0.5 part by weight or more based on 100 parts by weight of the total amount of the alkenyl halide (1) and the alkenyl mercaptan (2).
Claims4
A process for producing a compound represented by the formula (2):
- wherein R1 and R2 are independently hydrogen atom or a C1-4 alkyl group, comprising reacting a compound represented by the formula (1):
- wherein X is chlorine atom, bromine atom or iodine atom and R1 and R2 mean the same as defined above,
- with an alkali hydrosulfide, wherein said reaction is carried out in the presence of a compound represented by the formula (3):
- wherein R1 and R2 mean the same as defined above,
- in an amount of 0.5 part by weight or more based on 100 parts by weight of the total amount of the compounds represented by the formulae (1) and (2).
2 more elements
A process for stabilizing a compound represented by the formula (2):
- wherein R1 and R2 are independently hydrogen atom or C1-4 alkyl group, wherein 0.5 to 6.0 parts by weight of a compound represented by the formula (3):
- wherein R1 and R2 mean the same as defined above,
