Yintoni iSalicylic acid?
I-Salicylic acid yincindi yegxolo le-willow yesityalo, kwaye ikwayi-anti-inflammatory yendalo.
I-salicylic acid isetyenziswa kakhulu kunyango lwezifo ezahlukeneyo zesikhumba ezingapheliyo kwi-dermatology,ezifana ne-acne (i-acne), i-ringworm njalo njalo.
I-salicylic acid inokususa i-horny, i-sterilization, i-anti-inflammatory, nto leyo efanelekileyo kakhuluukunyanga i-acne ebangelwa kukuxinana, iimveliso eziphambili zehlabathi ze-acne zii-salicylic acid, uxinaniso ludla ngokuba yi-0.5 ukuya kwi-2%.
Umsebenzi weSalicylic acid
I-salicylic acid ingasetyenziswa njengezinto zokwenza amayeza. Ukulungiselela i-aspirin,i-sodium salicylate, i-salicylamide, i-analgesic, i-phenyl salicylate, kunye nezinye. Ishishini ledayi le-ukulungiswa kwe-moxibustion etyheli ecocekileyo, i-3GN emdaka ngqo, i-acid chrome etyheli njalo njalo.Ikwasetyenziswa njenge-raber vulcanization retarder kunye ne-disinfectant preservatives

Ukusetyenziswa kweSalicylic acid
1. I-salicylic acid ekuthiwa yi-ortho hydroxy benzoic acid (i-o-hydroxybenzoic acid) luhlobo lwe-izinto eziluhlaza ezibalulekileyo ezenziwe ngezinto eziphilayo.Kwimveliso yezibulali-zinambuzane, isetyenziselwa i-Isocarbophos, i-synthetic phosphorus organic pesticide,i-isofenphos methyl intermediate isopropyl salicylate kunye ne-Rodenticide warfarin, zibulala iimpuku i-etheri-intermediate 4-hydroxy coumarin; kwishishini lamayeza, i-salicylic acid yayisetyenziswa njengeii-antiseptics, ezikwasetyenziswa njengezinto eziphakathi kwe-acetylsalicylic acid (aspirin) kunye nezinye iziyobisi; ikwayi-antisepticizinto ezibalulekileyo zedayi, iziqholo, ezifana nemizi-mveliso yerabha.
2. Isetyenziswa kakhulu njengezinto ezisetyenziswa njengezinto zokutya ze-aspirin kunye ne-amine yamanzi yezinambuzane kunyeiimveliso ze-phosphorus, zingasetyenziswa nakwishishini ledayi, ukucokisa kunye ne-reagent yeekhemikhali, njl.
3. Isetyenziswa kwishishini lamayeza kwiyeza lokuthintela ukudumba, iintlungu, ukudumba,amayeza okukhupha isisu, idayi yemizi-mveliso esetyenziselwa iidayi ze-azo ngqo kunye needayi ze-acid mordant, kodwa nakwiziqholo, njl.
4. Isetyenziswa njengesalathisi esiyinkimbinkimbi kunye nesigcina-zimo.
5. Ukuqinisekiswa kwe-aluminium, i-boron, i-cerium, i-copper, i-iron, i-lead, i-manganese, i-mercury, i-nickel, isilivere,
i-titanium, i-tungsten, i-vanadium, i-sulfite, i-nitrate kunye ne-nitrite. Ukumiselwa kwe-aluminium, ubhedu, isinyithi,i-thorium, i-titanium kunye ne-uranium. Indlela ye-alkali kunye nomgangatho we-iodometry titration. I-fluorescentIsalathisi. Isalathisi esintsonkothileyo.| Into | Isalathiso |
