2. Ubuninzi: 1.119 g/cm³
4. I-Solubility: I-3-chloro-4-methylpyridine i-soluble kwi-solvents eninzi yezinto eziphilayo kwaye ayinyibiliki emanzini.
Usetyenziso oluphambili lwe-3-chloro-4-methylpyridine lulandelayo:
1. I-Synthesis ye-transition metal complexes: Yinto ebalulekileyo ephakathi esetyenziswe kwi-chemistry yokulungelelanisa ukudibanisa i-amino alcohols, i-amino alkates, kunye nezinye i-nitrogen heterocyclic compounds.
2. I-Pesticide intermediates: I-3-chloro-4-methylpyridine ingasetyenziswa njengendawo ephakathi kwezinye ii-insecticides kunye ne-herbicides.
Indlela yokulungiselela i-3-chloro-4-methylpyridine idla ngokubandakanya la manyathelo alandelayo:
1. Impendulo ye-nitroation ye-pyridine: i-pyridine iphendulwa nge-nitric acid egxininisiweyo kunye ne-sulfuric acid ukufumana i-3-nitropyridine.
2. Ukusabela kokunciphisa: I-3-nitropyridine iphendulwa ngokugqithisileyo kwe-sulfoxide kunye ne-agent yokunciphisa (njenge-zinc powder) ukufumana i-3-aminopyridine.
3. I-Chlorination reaction: I-3-aminopyridine iphendulwa nge-thionyl chloride ukufumana i-3-chloro-4-methylpyridine.
Ulwazi olufanelekileyo lokhuseleko lwe-3-chloro-4-methylpyridine lulandelayo:
1. Ukwazisa: Isenokuba ne-allergenic reaction kubantu abathile.
2. Ukucaphuka: Inokuba nefuthe elicaphukisayo emehlweni, inkqubo yokuphefumla kunye nolusu.
3. Ubuthi: Inetyhefu kwimpilo yabantu kwaye kufuneka ilandele iinkqubo ezifanelekileyo zokusebenza zokhuseleko.
4. Ugcino: Kufuneka igcinwe kwisikhongozeli esingangeni moya, kude nendawo ekutshiselwa kuyo nezinto ezixutyiweyo, kwaye kude nokudibana nomoya.
Xa usebenzisa i-3-chloro-4-methylpyridine, landela iiprothokholi ezifanelekileyo zokhuseleko ezifana nokunxiba i-eyewear ekhuselayo, iiglavu kunye nempahla ekhuselayo, kwaye uqinisekise ukuba iqhutywa kwindawo engena umoya. Kwimeko yokunxibelelana ngengozi okanye ukuphefumla, funa unyango ngokukhawuleza kwaye ubonise iPhepha leDatha loKhuseleko kugqirha wakho.
