Kev Siv
TBHP yog ib qho khoom siv nruab nrab hauv kev tsim cov propylene oxide thiab t-butyl cawv los ntawm isobutane thiab propylene. Nws feem ntau yog siv ua tus pib thiab tus catalyst tiav hauv cov tshuaj thiab emulsion polymerization txoj kev rau polystyrene thiab polyacrylates. Lwm yam kev siv yog rau polymerization ntawm vinyl chloride thiab vinyl acetate thiab ua tus catalyst oxidation thiab sulfonation hauv kev ua kom dawb thiab tshem tawm ntxhiab. Nws yog ib qho oxidant muaj zog thiab reacts hnyav nrog cov khoom siv hluav taws xob thiab cov khoom siv txo qis, thiab cov hlau thiab sulfur compounds.
tert-Butyl hydroperoxide yog siv los ua tus pib rau kev hloov pauv radical thiab hauv ntau yam txheej txheem oxidation xws li epoxidation tsis muaj zog. Nws koom nrog osmium catalyzed vicinal hydroxylation ntawm olefins nyob rau hauv alkaline mob. Ntxiv mus, nws yog siv rau hauv catalytic asymmetric oxidation ntawm sulfides rau sulfoxides siv binaphthol ua chiral auxiliary thiab hauv oxidation ntawm dibenzothiophenes. Nws ua lub luag haujlwm tseem ceeb rau kev qhia txog peroxy pawg hauv organic synthesis.
