摘　　要：In this experiment, allyl isothiocyanate and isobutanol were used as raw materials, and allyl isobutyl thiocarbamate was synthesized by one-step polymerization at a certain temperature under the action of catalyst. In this paper, the experiments were carried out from the following four factors: the ratio of raw materials, the amount of catalyst, the reaction time and the protection of the reaction system, and the optimum synthesis conditions were determined. The yield of allyl isothiocyanate and isobutanol is greatly improved after the synthesis process is optimized by adding 100ml/100ml of allyl isothiocyanate and isobutanol, adding 0.8g of catalyst and keeping the temperature at 110℃ for 5 hours. The raw materials are recycled through vacuum distillation, and the purity of the purified product reaches high quality and the impurity content of the product is reduced. In short, the products synthesized by this process are all qualified products, and the content is much higher than other products in the same industry. The product has high yield and low price, has great market advantages, and is an economical and environment-friendly synthesis process.
