Cyclohexanethiol
# Cyclohexanethiol

Cyclohexanethiol is a thiol with the formula $C_6H_{11}SH.$ It is a colorless liquid with a strong odor.

## Preparation

It was first prepared by the free-radical reaction of cyclohexane using carbon disulfide as a sulfur source.

It is produced industrially by the hydrogenation of cyclohexanone in the presence of hydrogen sulfide over a metal sulfide catalyst:

    $C_6H_{10}O$ + $H_2S$ + $H_2$ → $C_6H_{11}SH$ + $H_2O$

It is also obtained by the addition of hydrogen sulfide to cyclohexene in the presence of nickel sulfide.

## Safety

The $LD_{50}$ (injected, mice) was estimated at 316 mg/kg by the United States Department of Health, Education, and Welfare.
