Description

Fenobucarb is a carbamate ester obtained by the formal condensation of 2-sec-butylphenol with methylcarbamic acid.

Fenobucarb is a carbamate ester obtained by the formal condensation of 2-sec-butylphenol with methylcarbamic acid. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor, an agrochemical, a herbicide, an insecticide and an environmental contaminant. It derives from a methylcarbamic acid and a 2-sec-butylphenol.

Fenobucarb Use and Manufacturing

Methods of Manufacturing

Hydrocarbonated phenol, 1, n-butene react under the catalysis of sulfuric acid, the ratio is 1:1.4 (mol), the reaction temperature is 134 ~ 136 ℃; AlCl3 can also be used as a catalyst for the continuous synthesis of o-sec-butylphenol in the gas phase. Esterification: Toluene is cooled to below 0°C, a suitable amount of phosgene is added, and then o-sec-butylphenol treated by distillation is added, and sodium hydroxide solution is added dropwise to control the reaction temperature to be less than 0°C and the final pH value is 6-7. Obtained o-sec-butyl chloroformate. For ammonolysis, first cool o-sec-butylphenyl chloroformate to -10℃, start adding monomethylamine and sodium hydroxide solution dropwise, make the temperature <0℃, the final pH value is 7-8, continue to hold for 0.5h, and make the reaction Completely, toluene is recovered by desolvation to obtain the product Zhongdingwei.

Uses

Fenobuccarb is a carbamate insecticide used as an agricultural insecticide on rice and cotton.
