Phenothiazine yog ib qho nruab nrab ntawm cov tshuaj zoo xws li tshuaj thiab dyes. Nws yog ib qho ntxiv rau cov khoom siv hluavtaws (ib qho inhibitor rau kev tsim cov Vinylon), tshuaj tua kab rau txiv hmab txiv ntoo thiab demintic rau tsiaj. Nws muaj txiaj ntsig zoo rau stomatostoma vulgaris, nodoworm, stomatostoma, nematostoma Shari thiab nematostoma zoo caj dab ntawm yaj.
Nws yog tsuas yog siv los ua ib qho inhibitor ntawm acrylic acid, acrylic ester, methacrylic acid thiab ester monomer.
Lub npe Thiodiphenylamine. Feem ntau yog siv los ua ib qho inhibitor rau acrylic acid ntau lawm. Nws kuj tseem siv rau hauv kev sib xyaw ntawm cov tshuaj thiab cov tshuaj pleev xim, nrog rau cov khoom siv rau cov khoom siv hluavtaws (xws li inhibitor ntawm vinyl acetate grease, raw khoom ntawm roj hmab antioxidant). Kuj tseem siv los ua tshuaj tua kab mob rau cov tsiaj nyeg, txiv hmab txiv ntoo ntoo tshuaj tua kab.
Cov khoom no yog dav siv nyob rau hauv zus tau tej cov acrylic acid, acrylic ester, methacrylate thiab vinyl acetate raws li ib tug zoo heev inhibitor ntawm alkenyl monomer.
