Intshayelelo
Yikhompawundi ye-organic kunye ne-chemical formula C5H5ClN2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
Lulwelo olungenambala ukuya kumthubi olunevumba elikhethekileyo. Inomlinganiselo ophantsi wokubilisa kunye neqondo lokunyibilika kwiqondo lokushisa. Iyanyibilika kwizinyibilikisi zendalo ezifana nediethyl ether, iacetone kunye nedichloromethane.
Sebenzisa:
Yinto ebalulekileyo ye-organic intermediate, enokuthi isetyenziswe ngokubanzi kwi-synthesis yamachiza kunye ne-pesticides. Isetyenziswa njengendawo ephakathi ekudibaneni kweentlobo ngeentlobo zamachiza afana neziyobisi ezilwa nentsholongwane kunye neziyobisi ezilwa ne-antitumor. Ukongeza, ingasetyenziselwa ukulungisa ezinye izinto eziphilayo, ezifana nedayi kunye neekhompawundi zokulungelelanisa.
Indlela:
Indlela yokulungiselela i-calcium inokufumaneka ngokuphendula i-2-methyl pyrimidine nge-thionyl chloride. Iimeko ezithile zokusabela zinokuhlengahlengiswa ngokweemfuno zovavanyo, kodwa iimeko eziqhelekileyo zenziwa phantsi kwe-inert atmosphere, ubushushu begumbi okanye ukufudumeza.
Ulwazi ngoKhuseleko:
Inobuthi obuphantsi phantsi kweemeko zokusetyenziswa Jikelele, kodwa amanyathelo afanelekileyo okukhusela asafuneka. Ngexesha lokusebenza, ukudibana nolusu, amehlo kunye nokuphefumla umphunga kufuneka kugwenywe, kwaye iiglasi zokukhusela kunye neiglavu kufuneka zigqitywe xa kuyimfuneko. Ukuba udibana nale khompawundi, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango. Kwangaxeshanye, kuphephe ukuyixuba nee-oxidants ezinamandla kunye ne-acids ezomeleleyo ukuphepha umlilo okanye ugqabhuko-dubulo. Ukugcinwa kufuneka kubekwe kwindawo eyomileyo, epholileyo, nengena umoya kakuhle, kude nomlilo kunye nezinto ezinokutsha.
