Nhanganyaya
p-Chlorovalerophenone(p-Chlorovalerophenone) is an organic compound ine kemikari formula C11H13ClO. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzira uye ruzivo rwekuchengetedza:
Zvakasikwa:
p-Chlorovalerophenone imvura isina ruvara kuenda kuchiedza yero ine yakakosha ketone hwema. Iine density ye 1.086g/cm³, nzvimbo yekubikira ye245-248 ° C, uye flash point ye101 ° C. Haina kunyungudika mumvura, inonyungudika mudoro uye ether solvents.
Shandisa:
p-Chlorovalerophenone ine zvakawanda zvinoshandiswa mumunda wemakemikari. Inogona kushandiswa seyepakati mune organic synthesis yekubatanidza mamwe makomisheni. Mukuwedzera, inogonawo kushandiswa mukugadzira mishonga yezvipembenene, dhayi nemishonga.
Nzira:
p-Chlorovalerophenone inogona kugadzirwa neacylation reaction. Imwe nzira yakajairika ndeyekuita p-chlorobenzaldehyde nepentanone pasi pemamiriro ane acidic kuita p-Chlorovalerophenone.
Zvekuchengetedza
p-Chlorovalerophenone inogumbura ganda uye maziso, kuonana kwakananga kunofanira kudziviswa. Midziyo yekudzivirira yega senge magurovhosi ekudzivirira uye magogi anofanira kupfekwa panguva yekushandiswa. Panguva imwecheteyo, kutarisisa kunofanira kubhadharwa kudzivirira moto uye njodzi dzinoputika, uye kusangana neakasimba oxidants kunofanira kudziviswa. Paunenge uchichengeta, p-Chlorovalerophenone inofanira kuchengetwa munzvimbo inotonhorera, yakaoma uye ine mhepo yakanaka, kudzivisa kusvibiswa kwezuva. Kana ukafemerwa kana kumwiwa, tsvaga kurapwa nekukasika.
