Taw qhia
p-Chlorovalerophenone (p-Chlorovalerophenone) yog ib qho organic compound nrog cov tshuaj formula C11H13ClO. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev tsim thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
p-Chlorovalerophenone yog cov xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw tshwj xeeb ketone. Nws muaj qhov ntom ntawm 1.086g / cm³, qhov kub ntawm 245-248 ° C, thiab lub teeb nyem ntawm 101 ° C. Nws yog insoluble hauv dej, soluble hauv cawv thiab ether solvents.
Siv:
p-Chlorovalerophenone muaj ntau yam siv nyob rau hauv cov tshuaj. Nws tuaj yeem siv los ua qhov nruab nrab hauv cov organic synthesis rau kev sib txuas ntawm lwm cov tebchaw. Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv kev tsim cov tshuaj tua kab, dyes thiab tshuaj.
Txoj kev:
p-Chlorovalerophenone tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv acylation. Ib txoj hauv kev yog ua kom p-chlorobenzaldehyde nrog pentanone nyob rau hauv acidic tej yam kev mob los tsim p-Chlorovalerophenone.
Cov ntaub ntawv kev nyab xeeb:
p-Chlorovalerophenone irritating rau ntawm daim tawv nqaij thiab ob lub qhov muag, kev sib cuag ncaj qha yuav tsum raug zam. Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav thaum siv. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj rau kev tiv thaiv hluav taws thiab kev phom sij tawg, thiab kev sib cuag nrog cov oxidants muaj zog yuav tsum zam. Thaum khaws cia, p-Chlorovalerophenone yuav tsum muab cia rau hauv qhov chaw txias, qhuav thiab qhov cua zoo, tsis txhob raug tshav ntuj. Yog nqus tau los yog nqus tau, nrhiav kev kho mob tam sim ntawd.
