Daim ntawv thov
1. Butyric anhydride yog ntau yam acylating tus neeg sawv cev siv los ua ke butyrate esters rau cov tshuaj tsw qab, tsw, thiab tshuaj intermediates zoo li lub gallbladder sib piv tus neeg sawv cev iodopanoic acid.
2. Butyric anhydride CAS 106-31-0 ua cov khoom siv raw rau kev tsim cov cellulose acetate butyrate plastics, textile auxiliaries, varnishes, thiab tshuaj tua kab mob.
3. Butyric anhydride ua hauj lwm pab raws li ib tug fumigant tsav muv los ntawm khaus thiab yog siv nyob rau hauv kev tshawb fawb los npaj dye-sensitized solar cell Cheebtsam .
Cia thiab ceev faj
1. Khaws Butyric anhydride nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv inert gas nyob rau hauv ib tug txias, qhuav, zoo- qhov cua, raws li Butyric anhydride yog noo noo thiab huab cua rhiab heev.
2. Khaws Butyric anhydride CAS 106-31-0 nruj me ntsis kom deb ntawm cov khoom muaj zog oxidizing, muaj zog hauv paus, cawv, thiab amines, thiab tsis txhob muaj kev sib cuag nrog dej vim muaj kev kub ntxhov.
3. Kov Butyric anhydride siv cov cuab yeej tiv thaiv tus kheej tsim nyog suav nrog cov tshuaj lom neeg- cov hnab looj tes tiv thaiv (butyl- roj hmab), nruj nruj looj tsom iav nrog lub ntsej muag tiv thaiv, thiab hauv lub hood fume kom tsis txhob ua pa tawm.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav (tsawg kawg 50 meters / 150 ko taw rau cov kua), tshem tawm tag nrho cov khoom siv hluav taws xob, thiab muaj Butyric anhydride siv cov khoom siv tsis zoo xws li cov xuab zeb qhuav, npog nrog cov ntawv yas kom tiv thaiv kev sib cuag nrog los nag.
2. Sau cov absorbed Butyric anhydride CAS 106-31-0 siv tsis yog- cov cuab yeej hluav taws xob tawg mus rau hauv cov ntim ntim, cov ntawv lo tiv thaiv corrosion; Tsis txhob yaug nrog dej.
3. Cov neeg ua hauj lwm tu Butyric anhydride spills yuav tsum hnav cov khoom tiv thaiv tag nrho nrog rau tus kheej - muaj cov cuab yeej ua pa, tiv thaiv kev nkag mus rau hauv cov dej ntws los yog cov dej, thiab pov tseg cov khoom pov tseg raws li cov khoom siv phom sij (UN 2739, Chav Kawm 8, PG III).
Cov ntaub ntawv kev nyab xeeb
1. Butyric anhydride yog corrosive (GHS05, Danger), ua rau cov tawv nqaij kub hnyiab thiab qhov muag loj (H314, H318), nrog rau NFPA kev ntsuam xyuas kev noj qab haus huv ntawm 3 (kev phom sij loj).
2. Butyric anhydride CAS 106-31-0 yog cov kua combustible (H227) nrog lub teeb nyem ntawm 87-90℃(188-190℃F), reacts hnyav nrog dej los tsim butyric acid, thiab tej zaum yuav muaj teeb meem yog nqos tau (H302, LD50, 7 mg / kgrat.
3. Kev sib txuas ntawm Butyric anhydride ua rau cov pa roj carbon oxides lom; Butyric anhydride tej zaum yuav corrosive rau hlau (H290) thiab tej zaum yuav ua rau lub cev puas tsuaj (lub ntsws) los ntawm ib tug raug (H371).
