Isingeniso

 

Ikhwalithi:

I-2,4-Dichlorobenzoyl chloride iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile olunephunga elimnandi. Ayizinzile ekamelweni lokushisa futhi i-hydrolyzed kalula futhi ibole, ngakho kufanele igcinwe ngaphansi kwegesi ye-inert. Ihlangana nama-hydrocarbons, ama-amine anephunga elimnandi, notshwala ukuze kwakheke ama-amide nama-ester ahambisanayo.

 

Sebenzisa:

I-2,4-Dichlorobenzoyl chloride iyingxenye ebalulekile ekuhlanganiseni kwe-organic synthesis futhi inohlu olubanzi lwezinhlelo zokusebenza ekuphenduleni kwe-organic synthesis. Ingasetshenziswa ekulungiseleleni okuphuma ezinhlobonhlobo ze-benzoyl chloride nezinye izinhlanganisela eziphilayo.

 

Indlela:

I-2,4-Dichlorobenzoyl chloride ingatholwa ngokuxutshwa kwe-p-nitrobenzoic acid noma i-p-aminobenzoic acid. Indlela eqondile iwukusabela i-p-nitrobenzoic acid noma i-p-aminobenzoic acid ne-thionyl chloride ukuze kutholwe umkhiqizo ophakathi nendawo, bese umkhiqizo ophakathi ubuye ufakwe i-chloride ukuze ekugcineni uthole i-2,4-dichlorobenzoyl chloride.

 

Ulwazi Lokuphepha:

I-2,4-Dichlorobenzoyl chloride iyinhlanganisela yezinto eziphilayo ezicasulayo futhi ezibolayo. Ukuqapha kufanele kuthathwe ngesikhathi sokusetshenziswa nokuphatha, ukugwema ukuthintana nesikhumba, amehlo, kanye nomgudu wokuphefumula. Izinto zokuzivikela ezifanele, njengamagilavu ​​zelabhu, izibuko, nezingubo zokuzivikela, kufanele zigqokwe phakathi nenqubo. Ukuthintana nezinto ezivuthayo kanye nama-oxidizing agents kufanele kugwenywe ukuvimbela umlilo noma ukuqhuma. Uma igcinwe futhi ithuthwa, kufanele ivalwe futhi igcinwe kude nomlilo nemithombo yokushisa.
