Phenol (CAS 108-95-2), tseem hu ua cov kua qaub carbolic lossis hydroxybenzene, yog qhov siab {{purity muaj cov khoom siv phenolic, Bisphenol A (BRA), cov nplaum), thiab cov nplaum. Nws cov versatility thiab kev ntseeg tau ua nws qhov tseem ceeb rau kev tsim tshuaj thiab loj- scread tsim ntau lawm.
Lub cev thiab tshuaj
Lub cev lub cev:
- Xeev & tsos: tsis muaj kob lossis dawb crystalline khoom; Industrial -} Qib Phenol feem ntau yog cov kua pob tshab. Oxidizes rau liab dawb ntawm huab cua kis.
- Solubility: soluble hauv ethanol thiab diethyl ether; me ntsis soluble hauv dej (~ 8.3 mL ntawm 25 degree).
- Melting / Boiling Cov Ntsiab Lus: 40.5 Degree / 181.7 Degree.
Tshuaj lom neeg cov khoom:
- Acidity: qaug zog acid (Paka ≈ 9.95); cov ntaub ntawv phenolates nrog cov hauv paus.
- Oxidation: yooj yim oxidizes rau quinones; Cov khw ntim khoom hauv cov txheej txheem qhuav, muaj qhov cua.
- Reactivity: Benzene Ring Undergoes Halogenation, nitration, thiab lwm yam hluav taws xob hloov cov kev cai;
Cov ntawv thov hauv Phenum Lein ntau lawm
- Phenol reacts nrog formaldehyde los tsim cov txheej txheem phenolic, uas tau siv dav hauv:
- Plywood thiab laminates
- Cov Hluav Taws Xob Cov Hluav Taws Xob thiab Rwb Thaiv Tsev
- Cov nplaum thiab txheej
- Tshaj li Retin ntau lawm, 99% muaj phenol tseem siv rau:
- BPA thiab Polycarbonate Plastics
- Epoxy Resin Synthesis
- Cov tshuaj nruab nrab, tshuaj tua kab mob, thiab ua kom tuag
