Kev npaj ntawm esters thiab amides: Esters thiab cov lus qhia tuaj yeem npaj tau los ntawm kev siv dej cawv thiab muaj feem cuam tshuam, uas tuaj yeem siv los tsim cov khoom siv ntau yam.
Kws Tshuaj Kho Mob: Vim nws cov kev cuam tshuam, nws tuaj yeem siv los txhim kho cov chaw tsim hluav taws xob, tshwj xeeb yog cov uas xav tau kev qhia ntawm FuranyL pawg.
Kev Tshawb Fawb Tshuaj: Feem ntau siv hauv kev tshawb fawb los tsim cov hluavtthetic tshiab thiab tshawb cov txheej txheem sib txuam nrog cov cylorides.
Khaws rau hauv qhov chaw txias, qhuav thiab zoo-ventilated tsev rau khoom.
Tseg deb ntawm hluav taws thiab cov khoom cua sov. Zam kev tshav ntuj ncaj qha.
Lub pob yog ntim.
Nws yuav tsum tau muab cais cais tawm los ntawm cov kua qaub thiab cov tshuaj noj, thiab kev sib xyaw sib xyaw yuav tsum tsis txhob zam.
Thaj chaw cia yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog los muaj cov to.
Thawv: Khaws 2-lim 2-plaub ntim rau hauv cov thawv ntim khoom ua los ntawm cov khoom siv tau, xws li iav lossis qee cov yas uas tiv taus corrosive. Nco ntsoov tias lub thawv ntim khoom tau sau kom meej.
Qhov kub thiab txias: khaws ntim rau hauv qhov chaw txias, qhuav qhov chaw kom deb ntawm lub hnub ci ncaj qha thiab kub. Qhov ntsuas kub feem ntau yog feem ntau 15-25 ° C (59-77 ° F).
Inert roj: yog tias ua tau, khw muag khoom hauv qab xws li arert, uas yuav ua rau cov pa dej noo thiab huab cua, uas yuav ua rau muaj kua qaub hydrochloric thiab tso tawm ntawm hydrochloric acid.
Zam kev sib cuag nrog dej: Txij li thaum 2-plaub xabOl chloride reacts nrog dej, thov xyuas kom meej tias thaj chaw cia tsis noo thiab lub thawv ntim khoom ntim.
Kev ceev faj kev nyab xeeb: khw muag khoom hauv qhov chaw muaj pa zoo ntawm cov khoom siv tsis sib xws xws li muaj cov hauv paus muaj zog, dej cawv thiab cov amines. Siv cov khoom tiv thaiv tus kheej tsim nyog (PPE) thaum tuav lub compound.
Pov tseg: Thaum cov khoom siv phom sij tsis xav tau lawm, thov pov tseg raws li cov cai hauv nroog.

Yog lawm, 2-Laberyl Chloride yog kev phom sij rau tib neeg. Nws tau cais raws li txoj kev xeb cov khoom thiab tuaj yeem ua rau cov tawv nqaij, ob lub qhov muag, thiab ua pa. Nov yog qee qhov phom sij tshwj xeeb cuam tshuam nrog 2-furyl chloride:
1. Cov tawv nqaij thiab qhov muag khaus: ncaj qha sib cuag nrog 2-furyl chloride tuaj yeem ua rau muaj kev cuam tshuam hnyav lossis hlawv. Hnav khaub ncaws tiv thaiv uas tsim nyog, hnab looj tes thiab hnab looj tes thaum kov cov compound no.
2. Kev ua pa nyuaj: Kev nqus pa ntawm vapor uas muaj kev npau taws, ua pa ua pa, ua rau mob ua pa thiab mob qog noj ntshav thiab caj pas. Nws raug nquahu kom muaj qhov cua muaj txiaj ntsig tsim nyog los yog siv lub ntsej muag zoo thaum raug rau cov tshuaj no.
3. Ashunity: 2-Furyl chloride reacts nrog dej tso pa roj acid, uas ntxiv rau kev pheej hmoo ntawm cov tshuaj tua hluav taws thiab ua pa.
4. Toxicity: Txawm hais tias cov ntaub ntawv lom neeg lom neeg yuav raug txwv, kis tau rau cov kab mob ansyl ntawm cov kev pheej hmoo noj qab haus huv thiab kev saib xyuas kev ceev faj.
Txhawm rau txo qis kev pheej hmoo, ib txwm ua raws li cov lus qhia kev nyab xeeb, PPE), thiab ua haujlwm hauv qhov chaw muaj cua zoo thaum tuav 2-furyl chloride. Yog tias tshwm sim, nrhiav kev kho mob tam sim ntawd.
