Abstract

Способ получения тиофена и 2-тиофентиола, включающий взаимодействие избыточного количества сероводорода с фураном при температуре 25°C и атмосферном давлении, отличающийся тем, что в реакционную смесь фурана и сероводорода вводят катализатор - пространственно-затрудненный о-бензохинон, который периодически регенерируют в токе кислорода воздуха.A method of producing thiophene and 2-thiophentiol, comprising reacting an excess amount of hydrogen sulfide with furan at a temperature of 25 ° C and atmospheric pressure, characterized in that a spatially hindered o-benzoquinone is introduced into the reaction mixture of furan and hydrogen sulfide, which is periodically regenerated in an oxygen stream air.
