2.2 mmanya na-aba ụba na alkoxylate sulfate
Mmanya na-egbu egbu na alkoxylate sulfate ya bụ klas nke sulfate ester surfactants nke a na-akwado site na mmeghachi omume sulfation nke mmanya hydroxyl otu na sulfur trioxide. Ngwaahịa a na-ahụkarị bụ sulfate mmanya na-aba ụba na mmanya na-egbu egbu polyoxygen Vinyl ether sulfate na mmanya na-aba ụba polyoxypropylene polyoxyethylene ether sulfate, wdg.
2.2.1 Sulfate mmanya na-aba ụba
Sulfate Alcohol Sulfate (AS) bụ ụdị ngwaahịa a na-enweta site na mmanya na-egbu egbu site na SO3 sulfation na mmeghachi omume neutralization. Mmanya na-egbu egbu nke a na-ejikarị bụ koko C12-14. A na-akpọkarị ngwaahịa a K12. Isi ihe na-arụ ọrụ n'ahịa bụ 28% ~ 30% ngwaahịa mmiri na ihe ndị na-arụ ọrụ karịa ngwaahịa ntụ ntụ 90%. Dị ka anonic surfactant nwere ọmarịcha arụmọrụ, K12 nwere ngwa na ncha eze, ncha, ihe ụlọ gypsum na biomedicine.
2.2.2 polyoxyethylene ether sulfate mmanya na-aba ụba
Ihe ọṅụṅụ mmanya polyoxyethylene ether sulfate (AES) bụ ụdị surfactant enwetara site na polyoxyethylene ether abụba abụba (EO na-abụkarị 1 ~ 3) site na SO3 sulfation na neutralization.
