Intshayelelo
I-p-Chlorovalerophenone (p-Chlorovalerophenone) i-organic compound kunye ne-chemical formula C11H13ClO. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
p-Chlorovalerophenone lulwelo olungenambala ukuya ekukhanyeni olutyheli olunevumba elikhethekileyo leketone. Inoxinano lwe-1.086g/cm³, indawo yokubila eyi-245-248 ° C, kunye ne-flash point ye-101 ° C. Ayinyibiliki emanzini, inyibilika etywaleni nakwizinyibilikisi ze-ether.
Sebenzisa:
I-p-Chlorovalerophenone inemisebenzi emininzi kwintsimi yeekhemikhali. Ingasetyenziswa njengendawo ephakathi kwi-organic synthesis ye-synthesis yezinye iikhompawundi. Ukongeza, ingasetyenziselwa ukwenza izitshabalalisi, idayi kunye namayeza.
Indlela:
i-p-Chlorovalerophenone inokulungiswa nge-acylation reaction. Enye indlela eqhelekileyo kukusabela i-p-chlorobenzaldehyde kunye ne-pentanone phantsi kweemeko ze-acidic ukwenza i-p-Chlorovalerophenone.
Ulwazi ngoKhuseleko:
i-p-Chlorovalerophenone ecaphukisa ulusu kunye namehlo, ukudibanisa ngokuthe ngqo kufuneka kugwenywe. Izixhobo zokuzikhusela ezinje ngeeglavu zokhuselo kunye neeglavu kufuneka zinxitywe ngexesha lokusetyenziswa. Ngelo xesha, ingqalelo kufuneka ihlawulwe ekukhuseleni umlilo kunye neengozi zokuqhuma, kwaye ukudibanisa nee-oxidants ezinamandla kufuneka kugwenywe. Xa ugcina, i-p-Chlorovalerophenone kufuneka igcinwe kwindawo epholileyo, eyomileyo kwaye engenamoya, ukuphepha ukukhanya kwelanga. Ukuba uphefumlelwe okanye ukutyile, funa unyango ngokukhawuleza.
