2. Volatile, heev flammable, soluble nyob rau hauv organic solvents thiab inorganic acids.
Kev siv:
1. Raws li cov organic hnyav siv dav hauv kev lag luam tshuaj, nws ua lub luag haujlwm tseem ceeb hauv kev tshem tawm cov kuab tshuaj, degreasing, thiab npaj cov tshuaj ntxuav.
2. Biphenyltseem tuaj yeem siv los ua cov khoom siv raw thiab nruab nrab rau ntau yam tshuaj lom neeg, siv rau hauv kev sib xyaw ntawm dyes, plastics, roj hmab thiab lwm yam khoom.
3. Nws kuj tseem siv tau los ua cov khoom siv roj ntxiv, lub tshuab cua txias, thiab cov khoom tiv thaiv cov nroj tsuag.
Txoj kev:
Muaj ntau txoj hauv kev, feem ntau yog qhov tawg ntawm cov coal tar. Los ntawm cov thee tar tawg cov tshuaj tiv thaiv, ib feem sib xyaw uas muaj biphenyl tuaj yeem tau txais, thiab tom qab ntawd high-purity biphenyl tuaj yeem tau los ntawm kev ua kom huv thiab sib cais.
Cov ntaub ntawv kev ruaj ntseg:
1. Biphenylyog cov kua nplaum uas tuaj yeem ua rau hluav taws kub thaum raug hluav taws kub lossis kub kub. Yog li ntawd, nws yog ib qho tseem ceeb kom nyob deb ntawm qhov qhib nplaim taws, qhov chaw tshav kub, thiab hluav taws xob zoo li qub.
2. Biphenyl vapor muaj qee yam toxicity thiab tuaj yeem ua rau lub ntsws ua pa, lub paj hlwb, thiab tawv nqaij. Yog li ntawd, cov cuab yeej tiv thaiv tsim nyog yuav tsum tau hnav thiab qhov chaw ua haujlwm zoo ventilated yuav tsum tau ua kom ntseeg tau.
3. Biphenyls kuj tuaj yeem ua rau cov kab mob hauv dej puas tsuaj, yog li lawv yuav tsum raug zam kom tsis txhob raug tso rau hauv dej.
4. Thaum tuav thiab khaws cia biphenyls, yuav tsum ua raws li cov txheej txheem kev nyab xeeb uas cuam tshuam rau kev ua haujlwm kom tsis txhob muaj kev sib tsoo thiab kev sib tsoo.
