Daim ntawv thov
1. Propionyl bromide yog ib qho tseem ceeb acylating reagent siv nyob rau hauv cov organic synthesis los qhia cov propionyl pawg rau hauv lub hom phiaj molecules.
2. Propionyl bromide CAS 598-22-1 yog ib qho tseem ceeb nruab nrab rau kev npaj cov tshuaj sib xyaw thiab cov tshuaj agrochemicals.
3. Propionyl bromide yog siv rau hauv polymer chemistry rau kev hloov kho cov khoom siv thiab hauv analytical chemistry rau derivatizing cawv thiab amines.
Cia thiab ceev faj
1. Khaws Propionyl bromide nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv ib qho chaw txias, qhuav, zoo- qhov cua qhov chaw, deb ntawm tshav kub, sparks, thiab qhib nplaim taws.
2. Khaws Propionyl bromide CAS 598-22-1 nruj me ntsis kom deb ntawm dej, muaj zog oxidizing cov neeg ua haujlwm, thiab cov hauv paus, raws li Propionyl bromide reacts hnyav nrog dej.
3. Kov Propionyl bromide siv cov cuab yeej tiv thaiv tus kheej tsim nyog suav nrog tshuaj lom neeg - hnab looj tes tiv thaiv, daim npog ntsej muag, thiab hauv lub hood fume, kom ntseeg tau tias tawg - cov khoom pov thawj yog siv .
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab muaj cov kua Propionyl bromide siv cov khoom siv tsis zoo xws li cov xuab zeb qhuav, tiv thaiv kev sib cuag nrog dej.
2. Sau cov absorbed Propionyl bromide CAS 598-22-1 siv tsis yog- cov cuab yeej hluav taws xob tawg rau hauv cov ntim ntim, sau cov thawv tiv thaiv corrosion rau pov tseg raws li kev cai ib puag ncig.
3. Cov neeg ua haujlwm tu Propionyl bromide spills yuav tsum hnav cov cuab yeej tiv thaiv tag nrho suav nrog tus kheej - muaj cov cuab yeej ua pa, vim Propionyl bromide raug cais rau kev thauj mus los ua cov kua hluav taws xob corrosive (UN 2920, Hazard Class 8/3, PG II).
Cov ntaub ntawv kev nyab xeeb
1. Propionyl bromide yog corrosive thiab flammable (GHS05/GHS02, Danger), ua rau cov tawv nqaij kub hnyiab heev, qhov muag puas loj (H314), thiab yog ib tug flammable kua thiab vapor (H226, flash point 52 degree).
2. Propionyl bromide CAS 598-22-1 reacts hnyav nrog dej (EUH014), tso corrosive gases; Kev nqus pa tuaj yeem ua rau muaj kev raug mob corrosive rau lub ntsws thiab lub ntsws.
3. Kev sib xyaw ntawm Propionyl bromide ua rau cov pa phem xws li carbon monoxide thiab hydrogen bromide, thiab Propionyl bromide yuav tsum tau khaws cia nrog lub thawv kaw kom nruj (P402+P404, P405).
