Preparation of 4-Chloro-3-methylphenol: it can be prepared by m-cresol and dichlorosulfuryl. You can add the m-cresol into the dichlorosulfuryl slowly with stirring. The reaction temperature should be controlled at 30-50 °C. And the reaction time is 16 hours. After the reaction, you should wash the product with water, then wash it with sodium carbonate solution until alkaline and wash with hot water to neutral at last. After separating the oil, you should dry the product with anhydrous calcium chloride. Then vacuum distillation the product after filtering the desiccant.
Uses of 4-Chloro-3-methylphenol: it can be used as preservative of baby cosmetics and protein shampoo. It also can be used in organic synthesis, such as dyes and film preservatives. And it can be used to get 2,6-dibromo-4-chloro-3-methyl-phenol. This reaction will need reagent NBS. The reaction time is 0.1 minute at reaction temperature of 5 °C. The yield is about 50%. It is a kind of solid phase reaction.
When you are using this chemical, please be cautious about it as the following:
It is highly flammable and harmful in contact with skin and if swallowed. And it is toxic by inhalation, in contact with skin and if swallowed and very toxic to aquatic organisms and. It has very serious irreversible effects and risk of serious damage to the eyes. In addition, it may cause sensitization by skin contact.
