Polyol phosphate

Ko te polyol Phosphate he momo matū matū me te tātai rāpoi o te po4hr1r2.

nga korero tino nui

Ingoa Hainamana: polyol phosphate

Polyglycerol phosphate

tātai rāpoi: po4hr1r2

Te ahua: he wai kore tae, he kowhai ranei

Ingoa: polyether phosphate

N1, N2 me N3 ka taea te 0, te 1 ranei.

Ko nga ahuatanga ahupūngao o tenei waahanga e whai ake nei:

Ka taea te wehewehea nga polyol phosphates ki nga momo e rua: momo A ko te polyoxyethylene ether phosphate, he whakapiri parauri; Ko te momo B he polyol phosphate kei roto i te hauota, he ranunga o nga pūhui polyhydroxy, he wai kirikiri pango. Ka heke te memehatanga o te waikawa ūkuikui waro noa i roto i te wai i te pikinga o te tau o te ngota waro-alkyl R. Ko nga monoesters me nga mea whakamate o nga esters phosphate he waikawa ka taea te whakapohehe i nga katote hauwai i roto i te wairewa wai; i roto i te reo kawakore, ka whakaterehia tenei pirau. Ahakoa he puhoi ake i te polyphosphate, he ngawari te whakamaarama i te teitei o te pāmahana me nga tikanga kawakore. Ko te reiti hauwai he 10 nga wa o tera i roto i te reo kore. Kia puta te hauwai, ka ngaro te waikura me te aukati unahi. Ka taea e te phosphate i hanga te whakakotahi me nga katote konupūmā i roto i te wai ki te hanga i te tauine konupūmā phosphate me te wairewa iti.

Ko te tikanga, ko te glycerol ka waikurahia e te phosphate katahi ka whakamaarama ki te waikawa phosphonic. Ko te tauhohenga waiora o te glycerol e whai ake nei: te whakaranu i te glycerol me te paura houra, te whakamahana ki te 150 ℃ i raro i te whakamarumaru o te hau koretake, katahi ka taapirihia te ethylene oxide ki te ethylene oxide kia rite ki te tauwehenga molar o te ethylene oxide ki te glycerol o 2:1, me te pupuri i te mahana o te 150-160 ℃. Ina tapirihia te ethylene oxide me te pupuri mo tetahi wa (penei i te 1.2 haora), ka taea te whakaaro kua oti te ethylene glycerol. I roto i tenei tukanga, ko te taapiri o te houra caustic mo te 0.1% o te tapeke o te glycerol me te ethylene oxide. Ko te esterification phosphonate o te polyoxyethylene ether me te glycerin i mahia i roto i te reactor i te ōwehenga papatipu o te 4.5:1, i whakamahana ki te 50 ℃, katahi ka whakaurua te phosphorus pentoxide ki roto i te reactor kia rite ki te ōwehenga papatipu o te phosphorus pentoxide / polyoxyethylene ether glycerol. 1:1.1 ~ 1.2, a ko te pāmahana kaore i neke ake i te 125 ~ 135 ℃. Whai muri i te taapiri o te phosphorus pentoxide, ka marama nga mea kei roto i te reactor i muri i te pupuri mo te wa roa, ko te tikanga kua oti te mahi esterification. Tāpirihia he wai hei whakamatao i te phosphate ki te kukū e hiahiatia ana mo te tatari. Ko te ara waihanga e whai ake nei:

Ina whakawerahia te r-0h + H3PO4 ki te hanga r-h2po4 + H20

(R-0) I whakaritea te 2po2h + H2O ma te whakamahana 2R OH + H3PO4

Ka tauhohe a Ro-pcl4 + 3H2O ki te hanga r-h2po4 + 4hcl

Ko te Ethylene glycol, te ethylene glycol monoethyl ether, te polyoxyethylene ether, te glycerol me te triethanolamine i whakamahana ki te 75-85 ℃ i raro i te whakaoho me te whakaranu, katahi ka ata taapirihia te phosphorus pentoxide. Whai muri i te whakaurunga o te phosphorus pentoxide, ka whakahaeretia te pāmahana tauhohenga i te 130-140 ℃ mo te 1-2 haora. i tapirihia he wai hei whakamatao i te ranunga waikawa phosphoric hua kia tae ki te rahui whakamatautau e tumanakohia ana. Ko te ōwehenga o nga tauhohenga he triethanolamine, a ko te ranunga tauhohenga pai ko 60:40 ~ 40:60 (ōwehenga papatipu). Ko te ōwehenga papatipu tino pai o te ethylene glycol, ethylene glycol monoether me te polyoxyethylene ether glycerol he 1:4:4. Ka taea te taapiri i te Ethylene glycol monoethyl ether kia rua nga wa, ka honoa tetahi ki te ethylene glycol me te polyoxyethylene ether glycerin i mua i te tauhohenga, me te taapiri atu i te waa pupuri o te 140 ℃.
