Polyol phosphate

ʻO ka polyol Phosphate he ʻano mea kemika me ke ʻano molekala o po4hr1r2.

ʻike pono

Inoa Pākē: polyol phosphate

Polyglycerol phosphate

ʻAno molekole: po4hr1r2

ʻO ke ʻano: ʻaʻohe waihoʻoluʻu a i ʻole melemele ka wai aniani

Alias: polyether phosphate

Hiki iā N1, N2 a me N3 ke 0 a i ʻole 1.

ʻO nā waiwai physicochemical o kēia ʻāpana penei:

Hiki ke hoʻokaʻawale ʻia nā polyol phosphates i ʻelua mau ʻano: ʻo ke ʻano A he polyoxyethylene ether phosphate, ʻo ia ka paʻi ʻeleʻele; ʻO ke ʻano B he polyol phosphate i loko o ka nitrogen, kahi hui ʻana o nā pūhui polyhydroxy, he wai ʻeleʻele ʻeleʻele. E emi ana ka solubility o ka waika phosphoric organik maʻamau i ka wai me ka hoʻonui ʻana o ka helu R alkyl carbon atom. ʻO nā monoesters a me nā mea make o nā esters phosphate he ʻakika a hiki ke hoʻoheheʻe i nā ion hydrogen i loko o ka wai wai; i loko o ke ʻano alkaline, ua wikiwiki kēia decomposition. ʻOiai ʻoi aku ka lohi ma mua o ka polyphosphate, maʻalahi ka hydrolyze ma ke kiʻekiʻe o ka mahana a me nā kūlana alkaline. ʻO ka nui o ka hydrolysis he 10 mau manawa o kēlā ma ke ʻano kuʻuna. Ke hiki mai ka hydrolysis, e nalowale ana ka corrosion a me ka pale ʻana. Hiki i ka phosphate i hana ke hui me na iona calcium i loko o ka wai e hana i ka unahi calcium phosphate me ka ha'aha'a loa.

Ke hoʻoponopono ʻana i ka haku mele i kēia paukū

ʻO ka mea maʻamau, ua hoʻoneʻe ʻia ka glycerol e ka phosphate a laila esterified me ka phosphonic acid. Penei ka hopena oxidation o ka glycerol: ka hui ʻana i ka glycerol me ka pauka caustic soda, ka hoʻomehana ʻana i 150 ℃ ma lalo o ka pale o ke kinoea inert, a laila hoʻohui i ka ethylene oxide i ka ethylene oxide e like me ka ratio molar o ka ethylene oxide i ka glycerol o 2:1, a mālama i ka mahana o 150-160 ℃. Ke hoʻohui ʻia ka ethylene oxide a mālama ʻia no kekahi manawa (e like me 1.2 h), hiki ke noʻonoʻo ʻia ua pau ka ethylene ethylene o ka glycerol. Ma kēia kaʻina hana, ʻo ka hoʻohui ʻana i ka soda caustic ma kahi o 0.1% o ka nui o ka glycerol a me ka ethylene oxide. ʻO ka phosphonate esterification o ka polyoxyethylene ether a me ka glycerin i lawe ʻia i loko o ka reactor ma ka nui o ka ratio o 4.5: 1, preheated i 50 ℃, a laila ua hoʻohui ʻia ka phosphorus pentoxide i loko o ka reactor e like me ka ratio nui o ka phosphorus pentoxide / polyoxyethylene ether glycerol. 1:1.1 ~ 1.2, a ʻaʻole ʻoi aku ka mahana ma mua o 125 ~ 135 ℃. Ma hope o ka hoʻohui ʻia ʻana o ka phosphorus pentoxide, ʻike ʻia ka mea i loko o ka reactor ma hope o ka paʻa ʻana no kekahi manawa, ʻo ia hoʻi ua pau ke kaʻina hana esterification. E hoʻohui i ka wai e hoʻomaʻalili i ka phosphate i ka manaʻo i koi ʻia no ka standby. ʻO ke ala synthetic penei:

Ke hoʻomehana ʻia ka r-0h + H3PO4 e hana i ka r-h2po4 + H20

(R-0) Ua hoʻomākaukau ʻia ʻo 2po2h + H2O ma ka hoʻomehana ʻana iā 2R OH + H3PO4

Hoʻopili ʻo Ro-pcl4 + 3H2O i ka hana ʻana i r-h2po4 + 4hcl

Ethylene glycol, ethylene glycol monoethyl ether, polyoxyethylene ether, glycerol a me triethanolamine i hoʻomehana ʻia i 75-85 ℃ ma lalo o ka hoʻoulu ʻana a me ka hui ʻana, a laila hoʻohui mālie ʻia ka phosphorus pentoxide. Ma hope o ka hoʻohui ʻia ʻana o ka phosphorus pentoxide, ua hoʻomalu ʻia ka mahana hopena ma 130-140 ℃ no 1-2 mau hola. ua hoʻohui ʻia ka wai e hoʻomoʻalili i ka hui ʻana o ka waikawa phosphoric a hiki i ka mea i manaʻo ʻia. ʻO ka lakio o nā reactants he triethanolamine, a ʻo ka hui ʻana o ka hopena maikaʻi loa ʻo 60:40 ~ 40:60 (mass ratio). ʻO ka lakio nui loa o ka ethylene glycol, ethylene glycol monoether a me ka polyoxyethylene ether glycerol he 1:4:4. Hiki ke hoʻohui ʻia ka Ethylene glycol monoethyl ether i ʻelua manawa, hoʻohui ʻia kekahi me ka ethylene glycol a me ka polyoxyethylene ether glycerin ma mua o ka hopena, a hoʻohui ʻia kekahi i ka wā paʻa o 140 ℃.

E hōʻemi i ka hoʻoponopono ʻana i nā koina maikaʻi no kēia paukū

E nānā i nā koi ʻenehana i hōʻike ʻia ma ke kūlana ʻoihana hg2228-91

ʻO ke ala ʻike o ka pelu ʻana i ka hoʻoponopono ʻana i kēia ʻāpana

Ua hana ʻia ka hoʻāʻo e like me ke ʻano i kuhikuhi ʻia ma ka maʻamau hg2228-91.

Loaʻa i nā huahana papa i nā phosphonates Organic (me nā mono organik a me nā bisphosphonates) a me ka phosphorus pentoxide (ka hana ʻana i ka waika phosphoric inorganic me ka wai), hiki ke titrated mau ʻia me ke ʻano neutralization.
