O-phenylphenol (OPP) yog ib hom tshuaj lom neeg tshiab tseem ceeb thiab cov khoom siv organic intermediates. Nws yog siv dav hauv kev ua kom tsis muaj menyuam, tiv thaiv xeb, luam ntawv thiab zas xim, surfactants, stabilizers thiab flame retardants ntawm cov yas tshiab, resins thiab cov ntaub ntawv polymer.
O-phenylphenol feem ntau yog siv los npaj o-phenylphenol formaldehyde resin, thiab los npaj cov kua roj vanish nrog dej zoo heev thiab alkali stability. Cov kua roj vanish no muaj zog thiab tiv taus huab cua, tshwj xeeb tshaj yog haum rau huab cua ntub thiab txias thiab nkoj hauv hiav txwv.
OPP yog ib yam khoom siv tiv thaiv zoo, siv tau rau kev tiv thaiv kab mob pwm ntawm txiv hmab txiv ntoo thiab zaub, kuj siv tau los kho txiv qaub, txiv laum huab xeeb, dib, txiv duaj, txiv lws suav, dib, tuaj yeem txo qhov lwj kom tsawg kawg nkaus. Tebchaws Askiv, Tebchaws Meskas thiab Canada tau tso cai siv ntau yam txiv hmab txiv ntoo, suav nrog txiv apples, txiv pears, txiv laum huab xeeb, thiab lwm yam.
Ib qho tshuaj chlorinated ntawm o-phenylphenol, 2-chloro-4-phenylphenol, siv ua tshuaj tua kab thiab tshuaj tua kab mob, thiab ua tshuaj tua kab mob rau kev tswj cov kab mob ntawm cov ntoo txiv hmab txiv ntoo. O-phenylphenol tau sulfonated thiab condensed nrog formaldehyde los ua cov tshuaj dispersant rau tshuaj tua kab.
Kev npaj ntawm 2-chloro-4-phenylphenol los ntawm OPP tuaj yeem siv ua tshuaj tua kab thiab tshuaj tua kab mob, OPP tuaj yeem siv los tsim cov non-ionic emulsifier thiab cov xim pleev xim, o-phenylphenol thiab nws cov ntsev sodium soluble hauv dej kuj tseem siv tau ua cov xim rau polyester fiber, triacetic acid fiber, thiab lwm yam.
(1) Kev tsim cov polyester uas tiv taus hluav taws
Dop0 tau siv ua cov khoom siv raw los cuam tshuam nrog itaconic acid los tsim ib qho nruab nrab, odop-bda, uas tuaj yeem hloov pauv ethylene glycol ib feem kom tau txais phosphorus tshiab uas muaj cov polyester hluav taws kub.
(2) Kev tsim cov nplaim taws retardant epoxy resin
Epoxy resin yog siv dav hauv cov nplaum, cov cuab yeej hluav taws xob, aerospace, coatings thiab cov ntaub ntawv sib xyaw ua ke vim nws cov khoom nplaum zoo heev thiab cov khoom rwb thaiv hluav taws xob. Xyoo 2004, kev siv epoxy resin hauv ntiaj teb tau txog ntau dua 200,000 tons / xyoo.
(3) Txhim kho cov organic solubility ntawm polymers
(4) Ua ib qho nruab nrab hauv kev tsim cov tshuaj antioxidant
(5) Cov khoom ruaj khov rau cov khoom siv polymer tsim
(6) Niam txiv uas ci ntsa iab
