Isingeniso
I-p-Chlorovalerophenone(p-Chlorovalerophenone) iyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali ethi C11H13ClO. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
I-p-Chlorovalerophenone iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elikhethekile le-ketone. Inobukhulu obungu-1.086g/cm³, indawo yokubilisa engu-245-248 ° C, kanye nephuzu elikhanyayo elingu-101 ° C. Ayincibiliki emanzini, inyibilika otshwaleni nasezincibilikisini ze-ether.
Sebenzisa:
I-p-Chlorovalerophenone inokusetshenziswa okuningi emkhakheni wamakhemikhali. Ingasetshenziswa njengendawo ephakathi ku-organic synthesis yokuhlanganiswa kwezinye izinhlanganisela. Ngaphezu kwalokho, ingasetshenziswa futhi ekwenzeni izibulala-zinambuzane, odayi kanye nemithi.
Indlela:
i-p-Chlorovalerophenone ingalungiswa ngokusabela kwe-acylation. Enye indlela evamile iwukusabela i-p-chlorobenzaldehyde ne-pentanone ngaphansi kwezimo ezine-acidic ukuze kwakhiwe i-p-Chlorovalerophenone.
Ulwazi Lokuphepha:
p-Chlorovalerophenone ecasula isikhumba namehlo, ukuthintana ngqo kufanele kugwenywe. Izinto zokuzivikela ezinjengamagilavu okuzivikela kanye nezibuko kufanele zigqokwe ngesikhathi sokusetshenziswa. Ngesikhathi esifanayo, kufanele kuqashelwe ukuvimbela umlilo kanye nezingozi zokuqhuma, futhi ukuxhumana nama-oxidants aqinile kufanele kugwenywe. Lapho ugcina, i-p-Chlorovalerophenone kufanele igcinwe endaweni epholile, eyomile futhi enomoya omuhle, ukugwema ukuchayeka elangeni. Uma uhogele umoya noma udliwe, funa usizo lwezokwelapha ngokushesha.
