Uses:
1. Diethyl sulfate is a highly reactive ethylating agent and is widely used in the production of dyes, medicines and other fine chemical products. It is also used in the synthesis of quaternary ammonium salts, as a dehydrating agent, volatile oil extractant, etc. Uses Chemicalbook ethoxylation reaction of phenols Uses It is used in medicine, dyes, fragrances, pesticides, etc. It is also used as an ethylating agent and ethylene sulfonation promoter. Diethyl sulfate is a mutagen commonly used in plant or microbial breeding. Diethyl sulfate can induce single-strand breaks in barley seed DNA.
2. There are many industrial production methods for medicine, dyes, fragrances and pesticides. 1. It is obtained by the reaction of ethanol and sulfuric acid. 2. It is obtained by the reaction of ether and chlorosulfonic acid. 3. Diethyl sulfate can be obtained by heating monoethyl sulfate or distilling it in the presence of a dehydrating agent. 4. Diethyl sulfate is obtained by the reaction of ethylene and sulfuric acid.
