Intshayelelo
I-methyl i-organic compound kunye ne-molecular formula C7H8N2O2 kunye ne-molecular weight of 148.15g / mol. Lulwelo olungenambala olunevumba elikhethekileyo.
Le khompawundi isetyenziswa ngokuqhelekileyo kwintsimi yeziyobisi zokwenziwa, izibulala-zinambuzane kunye nedayi. Ingasetyenziselwa njengendawo ephakathi kwi-synthesis yezinye iikhompawundi zezinto eziphilayo, ezifana: ne-synthetic insecticide dimethicarb.
Indlela yokulungiselela i-methyl ifumaneka ngokubanzi ngokusabela kwe-esterification. Indlela ethile yokusabela kwi-5-methyl pyrazole-3-carboxylic acid kunye ne-methanol, phambi kwe-catalyst efanelekileyo, ukufumana umkhiqizo ofunekayo.
Ngokumalunga nolwazi lokhuseleko, i-methyl lulwelo olunokutsha kwaye kufuneka lugcinwe kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu. Ngethuba lokusetyenziswa kunye nokugcinwa, kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa nolusu, amehlo kunye nomgudu wokuphefumula. Kwangaxeshanye, utyando kufuneka lunxibe izixhobo ezifanelekileyo zokukhusela, ezinje ngeeglavu, iiglasi kunye nemaski ekhuselayo. Ukuba utyiwe okanye urholile, funa unyango ngokukhawuleza.
