methyl hydrogen azelate, eo hape e tsejoang e le polycarboxylate, ke polymer ea bohlokoa e phahameng ea molek'hule. E na le litšobotsi tse latelang:
1. Lintho tsa 'mele: methyl hydrogen azelate ke mokelikeli o mosehla o se nang 'mala kapa o bobebe, o qhibiliha hantle, o qhibiliha ka metsing, joala le lihlapolli tsa tlhaho.
2. Lintho tsa lik'hemik'hale: methyl hydrogen azelate ke motsoako oa ester o nang le botsitso bo phahameng le ho hanyetsa lik'hemik'hale. E ka ba hydrolyzed ho azelaic acid le methanol.
Tšebeliso ea mantlha ea methyl hydrogen azelate e kenyelletsa:
1. Ho lokisoa ha polymer: methyl hydrogen azelate e ka etsoa polymerized le li-monomers tse ling ho lokisa li-polymers tse phahameng tsa molek'hule. Li-polymer tsena li na le thepa e ntle haholo 'me li ka sebelisoa liindastering tse fapaneng tse kang li-coatings, glues, polasetiki, fiber, joalo-joalo.
2. Surfactant: methyl hydrogen azelate e ka sebelisoa e le emulsifier, dispersant le wetting agent, e sebelisoang haholo litlolo, litlolo le lihlahisoa tsa tlhokomelo ea botho le masimo a mang.
Mekhoa ea ho lokisa methyl hydrogen azelate haholo-holo ke e latelang:
1. Phetoho ea transesterification: karabelo ea transesterification e etsoa ka joala ea nonyl le methyl formate boteng ba acid catalyst ho fumana methyl hydrogen azelate.
2. Karabelo e tobileng ea esterification: esterification ea nonanol le formate tlas'a ketso ea acid catalyst ho hlahisa methyl hydrogen azelate.
Ela hloko lintlha tse latelang tsa polokeho ha u sebelisa le ho tšoara methyl hydrogen azelate:
1. methyl hydrogen azelate e ea teneha 'me e lokela ho hlatsuoa hang-hang ha e kopana le letlalo le mahlo.
2. Qoba ho hema mouoane oa methyl hydrogen azelate le ho o sebelisa sebakeng se nang le moea o motle.
3. methyl hydrogen azelate e na le chefo e tlase, empa ho pepeseha ha nako e telele le ho hoholo ho ka ama bophelo bo botle, 'me ho pepeseha ho feteletseng ho lokela ho qojoa.
4. Ha u boloka le ho tsamaisa methyl hydrogen azelate, e boloke hole le mollo le mocheso o phahameng ho thibela kotsi ea ho cha le ho phatloha.
Ka kopo elelloa hore pele o sebelisa methyl hydrogen azelate kapa khemikhale efe kapa efe, o lokela ho bala ka hloko le ho latela mekhoa e nepahetseng ea ts'ireletso.
