Intshayelelo
IMethyl thiobutyrate. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-methyl thiobutyrate:
1. Indalo:
I-Methyl thiobutyrate lulwelo olungenambala kunye nevumba elibi elibi. Inokunyibilika kwii-alcohols, ii-ethers, ii-hydrocarbons, kunye nezinye izinyibilikisi eziphilayo.
2. Ukusetyenziswa:
I-Methyl thiobutyrate isetyenziswa kakhulu njengesithako kwi-pesticides kunye ne-insecticide, ngakumbi ekulawuleni izitshabalalisi ezifana neentuthwane, iingcongconi kunye neempethu zegalikhi. Isenokusetyenziswa njengendawo ephakathi kwi-organic synthesis yokwenziwa kwezinye iikhompawundi.
3. Indlela:
Ukulungiswa kwe-methyl thiobutyrate ngokuqhelekileyo kufumaneka ngokuphendula kwe-sodium thiosulfate kunye ne-bromobutane. Indlela ethile yokulungiselela yile ilandelayo:
I-sodium thiosulfate iphendulwa kunye ne-bromobutane phantsi kweemeko ze-alkali ukuvelisa i-sodium thiobutyl sulfate. Emva koko, phambi kwe-methanol, ukusabela kwe-reflux kushushu ukuze kufakwe i-sodium thiobutyl sulfate kunye ne-methanol ukuvelisa i-methyl thiobutyrate.
4. Ulwazi ngoKhuseleko:
I-Methyl thiobutyrate inetyhefu ephezulu. Inokuba yingozi kumzimba womntu kunye nokusingqongileyo. Ukuvezwa kwi-methyl thiobutyrate kunokubangela ukucaphuka kwesikhumba, ukucaphuka kwamehlo, kunye nokucaphuka kokuphefumula. Kwiindawo eziphezulu, iyavutha kwaye iqhume. Xa usebenzisa i-methyl thiobutyrate, amanyathelo okukhusela umntu kufuneka aqiniswe, ukudibanisa nolusu kunye namehlo kufuneka kugwenywe, kwaye ukusetyenziswa kwindawo yokuphefumula kakuhle kufuneka kuqinisekiswe. Ukongeza, izikhokelo ezifanelekileyo zokuphatha ukhuseleko kunye nemimiselo kufuneka ilandelwe ukuphathwa ngokufanelekileyo kunye nokugcinwa kwekhompawundi. Ukuba kukho naziphi na iimpawu zetyhefu, funa unyango ngokukhawuleza.
