Diethanolamine 111-42-2 puriy: ≥99%

Semelo:

Ethanolamine (EA) ke joala ba amino ba bohlokoa ka ho fetisisa, ho kenyeletsoa monoethanolamine (MEA), diethanolamine (DEA), le triethanolamine (TEA). Ethanolamine ke sesebelisoa sa bohlokoa sa tlhaho se sebelisoang haholo ho li-surfactants, li-detergent tsa maiketsetso, li-additives tsa petroleum, li-resin tsa maiketsetso le li-plasticizer tsa rabara, li-accelerator, li-vulcanizer le li-agent tse foam, hammoho le ho hloekiseng khase, ho thibela ho hoama ha metsi, ho hatisa le ho daea, meriana, chefo e bolaeang likokoanyana, kaho le lits'ebetsong tsa sesole. Lihlahisoa tse ngata tse tlase tsa ethanolamine ke li-intermediate tsa bohlokoa tsa lik'hemik'hale 'me le tsona li haella Chaena. Ka hona, boiteko bo eketsehileng nts'etsopele le ts'ebeliso ea ethanolamine bo bohlokoa ho fihlela tlhoko ea lik'hemik'hale tsa lapeng le ho khothaletsa nts'etsopele e potlakileng ea indasteri ea ethanolamine.

Diethanolamine, e tsejoang hape e le bishydroxyethylamine le 2,2′-iminobisethanol, ke mokelikeli o mosweu o kang kristale kapa o se nang mmala o nang le hygroscopicity e matla. E qhibiliha habonolo metsing, methanol, ethanol, acetone le benzene. Ho qhibiliha ha eona ka har'a benzene (g/100g) ho 25°C ke 4.2, 'me ka har'a ether ke 0.8. Tšebeliso ea eona e kenyelletsa: sesebelisoa sa ho hloekisa khase, se monyang likhase tse nang le asiti tse nang le lik'hemik'hale tse kang carbon dioxide, hydrogen sulfide le sulfur dioxide. Tharollo ea "Benfil", e sebelisoang indastering ea tlhahiso ea ammonia, e entsoe haholo-holo ka sehlahisoa sena. E boetse e sebelisoa e le emulsifier, lubricant, shampoo, thickener, le li-additives tse ling. Ke motsoako oa tlhaho o sebelisoang tlhahisong ea lisebelisoa tse tala tsa sesepa, li-preservative le lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi (joalo ka li-surfactants). E boetse e sebelisoa ho etseng morpholine.

Tšebeliso: Diethanolamine e sebelisoa e le thepa e tala bakeng sa li-buffer indastering ea meriana, e le moemeli oa ho hokahanya tlhahiso ea foam ea polyurethane e matla haholo, le e le sesepa sa li-piston tsa enjene ea lifofane ha li kopantsoe le triethanolamine. E arabela le li-acid tse mafura ho etsa alkyl alcohol acyl. E boetse e sebelisoa e le thepa e tala bakeng sa tlhahiso ea lintho tse phelang, thepa e tala ea buka ea lik'hemik'hale bakeng sa li-surfactants, le monya khase ea asiti. E sebelisoa e le sesebelisoa se teteaneng le se fetolang foam ka har'a li-shampoo le li-detergent tse bobebe, e le sesebelisoa se mahareng indastering ea tlhahiso ea lintho tse phelang, le e le tharollo indastering ea meriana. E na le mefuta e mengata ea ts'ebeliso indastering ea ho hlatsoa, ​​​​indastering ea litlolo, temong, indastering ea kaho le indastering ea tšepe.
