Dipropylene Glycol Dimethyl Ether na CAS 111109-77-4
Dipropylene Glycol Dimethyl Ether dị mkpụmkpụ as DPGDME, nke nwere nọmba CAS 111109-77-4, bụ ihe mgbaze aprotic polar a na-ejikarị eme ihe. Ihe mgbaze Dpdme nwere polarity dị ala, ọ na-agbaze ngwa ngwa na mmiri, a pụkwara ịgwakọta ya na ọtụtụ ihe mgbaze organic. Dipropylene glycol dimethyl ether bụ ihe mgbaze "water-organic phase" dị mma nke dabara na "mmiri-organic phase". Ihe mgbaze Dpdme bụ ihe mgbaze nke na-esi n'ọkụ, ọ naghị ere ọkụ mana ekwesịrị idobe ya ka ọ ghara ire ọkụ nke na-ekpo ọkụ nke ukwuu.
