China 2-Methoxyethanol CAS 109-86-4 imboni nabakhiqizi

I-2-Methoxyethanol CAS 109-86-4

incazelo emfushane:

I-Ethylene glycol monomethyl ether (efushanisiwe ngokuthi i-MOE), eyaziwa nangokuthi i-ethylene glycol methyl ether, iwuketshezi olungenambala futhi olusobala, oluxubene namanzi, utshwala, i-acetic acid, i-acetone ne-DMF. Njengesixazululi esibalulekile, i-MOE isetshenziswa kabanzi njengesixazululi samafutha ahlukahlukene, ama-cellulose acetates, ama-nitrate e-cellulose, odayi abancibilika ngotshwala kanye nama-synthetic resins.
Itholakala ngokusabela kwe-ethylene oxide ne-methanol. Faka i-methanol ku-boron trifluoride ether complex, futhi udlule ku-ethylene oxide ku-25-30°C ngenkathi ushukumisa. Ngemva kokuqedwa kokudlula, izinga lokushisa likhuphuka ngokuzenzakalelayo libe ngu-38-45°C. Isixazululo sokusabela esiwumphumela siphathwa nge-potassium hydrocyanide- Neutralize isixazululo se-methanol sibe pH=8-Chemicalbook9. Phinda uthole i-methanol, uyidilize, bese uqoqa izingxenyana ngaphambi kuka-130°C ukuze uthole umkhiqizo ongahluziwe. Bese wenza i-fractional distillation, bese uqoqa ingxenyenamba engu-123-125°C njengomkhiqizo oqediwe. Emkhiqizweni wezimboni, i-ethylene oxide ne-anhydrous methanol isabela ekushiseni okuphezulu nokucindezela ngaphandle kwe-catalyst, futhi umkhiqizo okhiqiza kakhulu ungatholakala.
Lo mkhiqizo usetshenziswa njenge-solvent yamafutha ahlukahlukene, i-lignin, i-nitrocellulose, i-cellulose acetate, odayi abancibilika ngotshwala kanye nama-synthetic resins; njenge-reagent yokunqunywa kwe-iron, i-sulfate ne-carbon disulfide, njenge-diluent ye-coatings, ne-cellophane. Kuma-package sealers, ama-varnishes omisa ngokushesha nama-enamel. Ingasetshenziswa futhi njenge-ejenti yokungena kanye ne-ejenti yokulinganisa embonini kadayi, noma njenge-plasticizer kanye ne-brightener. Njengesiphakathi ekukhiqizeni izinhlanganisela eziphilayo, i-ethylene glycol monomethyl ether isetshenziswa kakhulu ekuhlanganiseni i-acetate ne-ethylene glycol dimethyl ether. Kuphinde kube yi-Chemicalbook impahla eluhlaza yokukhiqizwa kwe-bis(2-methoxyethyl)phthalate plasticizer. Ingxube ye-ethylene glycol monomethyl ether ne-glycerin (i-ether: glycerin = 98:2) iyisengezo se-fuel jet yezempi engavimbela ukugqwala nokugqwala kwebhaktheriya. Uma i-ethylene glycol monomethyl ether isetshenziswa njenge-ejenti ye-jet fuel antisizing, inani elijwayelekile lokwengezwa ngu-0.15% ± 0.05%. Ine-hydrophilicity enhle. Isebenzisa iqembu layo le-hydroxyl kuphethiloli ukuze ihlanganyele nenani elincane lama-molecule amanzi kuwoyela. Ukwakheka kwe-hydrogen bond association, kuhambisana nendawo yayo yokuqanda ephansi kakhulu, kwehlisa indawo eqandisela amanzi emafutheni, okuvumela amanzi adlulele eqhweni. I-Ethylene glycol monomethyl ether nayo iyisengezo esilwa namagciwane.
