Intshayelelo

 

Umgangatho:

I-2,4-Dichlorobenzoyl chloride lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elibi. Ayizinzile kwiqondo lokushisa lokushisa kwaye i-hydrolyzed ngokulula kwaye ibolile, ngoko kufuneka igcinwe phantsi kwegesi ye-inert. Isebenza kunye neehydrocarbons, iiamines ezinuka kamnandi, kunye neealkoholi ukwenza iiamide ezihambelanayo kunye neeesta.

 

Sebenzisa:

I-2,4-Dichlorobenzoyl chloride yinto ebalulekileyo ephakathi kwi-organic synthesis kwaye inoluhlu olubanzi lwezicelo kwiimpendulo ze-organic synthesis. Ingasetyenziswa ekulungiseleleni iintlobo ezahlukeneyo ze-benzoyl chloride kunye nezinye iikhompawundi eziphilayo.

 

Indlela:

I-2,4-Dichlorobenzoyl chloride inokufumaneka nge-chlorination ye-p-nitrobenzoic acid okanye i-p-aminobenzoic acid. Indlela ethile kukusabela i-p-nitrobenzoic acid okanye i-p-aminobenzoic acid kunye ne-thionyl chloride ukufumana imveliso ephakathi, kwaye ke imveliso ephakathi iphinda ihlanjululwe ekugqibeleni ifumane i-2,4-dichlorobenzoyl chloride.

 

Ulwazi ngoKhuseleko:

I-2,4-i-Dichlorobenzoyl chloride yi-organic compound ecasulayo kunye ne-corrosion. Kufuneka kuthathwe amanyathelo okhuseleko ngexesha lokusetyenziswa kunye nokuphatha, ukuphepha ukudibanisa nolusu, amehlo, kunye nomgudu wokuphefumula. Izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu zelebhu, iiglasi, kunye nempahla yokukhusela, kufuneka zinxitywe ngexesha lenkqubo. Ukudibana nezinto ezinokutsha kunye nee-oxidizing agents kufuneka kuphetshwe ukuthintela umlilo okanye ugqabhuko-dubulo. Xa igcinwe kwaye ithuthwa, kufuneka ivalwe kwaye igcinwe kude nomlilo kunye nemithombo yobushushu.
