Process for producing pyridylethylthio compound, modified ion exchanger and process for producing the same, and process for producing bisphenol compound |
摘要 |
The present invention relates to a process for producing a pyridylethylthio compound which is improved in yield of the pyridylethylthio compound. In a process for producing a pyridylethylthio compound by reacting vinyl pyridine with a sulfur-containing compound, vinyl pyridine used contains a compound represented by the general formula (1): (wherein R1 and R2 are any of combination of isopropenyl group and a hydrogen atom, combination of 1-propenyl group and a hydrogen atom, combination of 2-propenyl group and a hydrogen atom, and combination of methyl group and vinyl group), in an amount of not more than 4% by weight.
