Selelekela
Acid (acid) ke motsoako oa organic o nang le foromo ea lik'hemik'hale C6H4ClNO2.
Tlhaho:
Asiti ke 'mala o mosoeu ho isa ho o mosehla o mosehla o tiileng ka monko o khethehileng. E qhibiliha ka har'a metsoako e meng ea tlhaho, joalo ka ethanol, dimethyl sulfoxide le dichloromethane, empa e na le ho qhibiliha ho tlase metsing. E tsitsitse moeeng 'me e senyeha ha mocheso o phahameng.
Sebelisa:
Asiti ke motsoako oa bohlokoa oa manyolo, o sebelisoang haholo ho kopanya metsoako e meng ea manyolo. E ka sebelisoa ho lokisetsa chefo e bolaeang likokoanyana, lithethefatsi, lidae le metsoako ea ho hokahanya.
Mokhoa oa ho itokisa:
Acid e ka etsoa ka mekhoa e fapaneng, mekhoa e sebelisoang hangata e kenyelletsa tse peli tse latelang:
1. 2-picolinic acid chloride e itšoara ka chloroacetic acid ho hlahisa sehlahisoa se lebisitsoeng ka thuso ea catalyst le tlas'a maemo a loketseng.
2. itšoara ka 2-pyridyl methanol ka carbonic acid chloride, 'me joale hydrolyze le asiti ho fumana acid.
Lintlha tsa Tšireletseho:
Chefo ea acid e tlase, empa ho ntse ho hlokahala ho ela hloko ts'ebetso e sireletsehileng. Qoba ho kopana ka kotloloho le letlalo, mahlo le phefumoloho, 'me u roale liatlana tse sireletsang, likhalase le limaske ha ho hlokahala. Qoba ho kopana le li-oxidizing agents le lintho tse tukang nakong ea tšebeliso le polokelo. E lokela ho bolokoa sebakeng se omileng, se nang le moea o motle, hole le mollo. Haeba motho a ka nooa kapa a hema, batla thuso ea bongaka hang-hang.
