Phenothiazine is an intermediate of fine chemicals such as drugs and dyes. It is an additive for synthetic materials (an inhibitor for the production of Vinylon), a pesticide for fruit trees and a demintic for animals. It has significant effect on the stomatostoma vulgaris, the nodoworm, the stomatostoma, the nematostoma Shari and the nematostoma fine neck of sheep.
It is mainly used as an efficient inhibitor of acrylic acid, acrylic ester, methacrylic acid and ester monomer.
Alias Thiodiphenylamine. Mainly used as an inhibitor for acrylic acid production. It is also used in the synthesis of drugs and dyes, as well as auxiliaries for synthetic materials (such as the inhibitor of vinyl acetate grease, the raw material of rubber antioxidant). Also used as a deworming drug for livestock, fruit tree insecticide.
This product is widely used in the production of acrylic acid, acrylic ester, methacrylate and vinyl acetate as an excellent inhibitor of alkenyl monomer.
