Process for producing hydroxyalkyl mercaptans

Abstract

Abstract PROCESSES OF REACTING HYDROGEN SULFIDE WITH A MONO OR POLY, TERMINAL OR NON-TERMINAL, ALIPHATIC OR CYCLOALIPHATIC EPOXIDES HAVING MORE THAN 3 CARBON ATOMS IN THE PRESENCE OF 0.01% TO 10% BY WEIGHT OF A STRONGLY BASIC CATALYST IN THE TEMPERATURE RANGE OF FROM -20*C. TO 200*C. AT NORMAL TO ELEVATED PRESSURES IN ORDER TO OBTAIN A HYDROXYALKYL MERCAPTAN CONTAINING MORE THAN 3 CARBON ATOMS. THE NOVEL PRODUCTS ARE HIGHER MOLECULAR WEIGHT HYDROXYALKYL MERCAPTANS OF THE FORMULA R1-C(-R2)(-OH)-CH(-R3)-SH WHEREIN R1 IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF ALKYL HAVING FROM 1 TO 22 CARBON ATOMS, ALKYLOL HAVING FROM 1 TO 22 CARBON ATOMS, ALKOXYALKYL HAVING FROM 2 TO 22 CARBON ATOMS, HALOALKYL HAVING FROM 1 TO 22 CARBON ATOMS, CYCLOALKYLALKYL HAVING FROM 6 TO 22 CARBON ATOMS AND ALKENYL HAVING FROM 3 TO 22 CARBON, R2 AND R3 ARE MEMBERS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND R1 AND, WHEN TAKEN TOGETHER, ALKYLENE HAVING FROM 3 TO 4 CARBON ATOMS, WITH THE PROVISO THAT THE SUM OF THE CARBON ATOMS IN R1, R2 AND R3 IS FROM 6 TO 22. THE NOVEL HYDROXYALKYL MERCAPTANS ARE USEFUL AS INSECTICIDES AND FUNGICIDES, EMULSIFIERS AND INTERMEDIATES IN CHEMICAL SYNTHESIS.
