O-phenylphenol (OPP) yog ib yam tshiab tseem ceeb ntawm cov khoom siv tshuaj zoo thiab cov organic intermediates. Nws yog dav siv nyob rau hauv kev ua kom tsis muaj menyuam, tiv thaiv corrosion, luam ntawv thiab dyeing auxiliaries, surfactants, stabilizers thiab nplaim retardants ntawm tshiab plastics, resins thiab polymer cov ntaub ntawv.
O-phenylphenol feem ntau yog siv los npaj o-phenylphenol formaldehyde resin, thiab npaj cov kua roj vanish nrog dej zoo thiab alkali stability. Cov kua roj vanish no muaj lub zog ruaj khov thiab tiv taus huab cua, tshwj xeeb tshaj yog haum rau huab cua ntub thiab txias thiab cov nkoj hauv hiav txwv.
Opp yog ib qho zoo preservative, yuav siv tau rau txiv hmab txiv ntoo thiab zaub mildew tiv thaiv, kuj yuav siv tau los kho txiv qaub, pineapple, melon, pear, txiv duaj, txiv lws suav, dib, yuav txo tau cov rot mus rau qhov tsawg kawg nkaus. Lub tebchaws United Kingdom, Tebchaws Meskas thiab Canada tau tso cai siv ntau yam txiv hmab txiv ntoo, suav nrog txiv apples, txiv duaj, txiv ntoo, thiab lwm yam.
Ib qho chlorinated derivative ntawm o-phenylphenol, 2-chloro-4-phenylphenol, siv los ua tshuaj tua kab mob thiab tshuaj tua kab mob, thiab ua cov tshuaj tua kab mob rau kev tswj cov kab mob ntoo txiv ntoo. O-phenylphenol yog sulfonated thiab condensed nrog formaldehyde los ua dispersant rau tshuaj tua kab.
Kev npaj ntawm 2-chloro-4-phenylphenol los ntawm OPP tuaj yeem siv los ua tshuaj tua kab mob thiab tshuaj tua kab mob, OPP tuaj yeem siv los tsim cov khoom tsis-ionic emulsifier thiab hluavtaws dyes, o-phenylphenol thiab nws cov dej-soluble sodium ntsev kuj tuaj yeem siv los ua xim cov cab kuj rau polyester fiber, triacetic acid fiber, thiab lwm yam,
(1) Synthesis ntawm nplaim retardant polyester
Dop0 tau siv los ua cov khoom siv raw los ua rau nws cov kua qaub los ua ib qho nruab nrab, odop-bda, uas tuaj yeem hloov pauv ethylene glycol kom tau txais cov phosphorus tshiab uas muaj cov nplaim hluav taws xob polyester.
(2) Synthesis ntawm nplaim retardant epoxy cob
Epoxy resin yog siv dav hauv cov nplaum, cov cuab yeej hluav taws xob, aerospace, coatings thiab cov ntaub ntawv zoo heev vim nws qhov zoo heev adhesion thiab hluav taws xob rwb thaiv tsev. Xyoo 2004, kev noj epoxy resin hauv ntiaj teb tau mus txog ntau dua 200000 tons / xyoo.
(3) Txhim kho cov organic solubility ntawm polymers
(4) Ua ib qho nruab nrab hauv kev sib txuas ntawm antioxidant
(5) Stabilizers rau cov khoom siv hluavtaws polymer
(6) Synthetic luminescent niam txiv
