Iyini i-salicylic acid?
I-salicylic acid iwukukhipha amagxolo e-willow, futhi iphinde ibe ne-anti-inflammatory yemvelo.
I-salicylic acid evame ukusetshenziswa ekwelapheni izifo ezahlukahlukene zesikhumba ezingapheli ku-dermatology,njengezinduna (izinduna), umbandamu nokunye.
I-salicylic acid ingasusa i-horny, inzalo, i-anti-inflammatory, efanelekile kakhuluekwelapheni induna ebangelwa ama-clogs, imikhiqizo ye-acne ejwayelekile emhlabeni jikelelei-salicylic acid, ukuhlushwa kuvame ukuba ngu-0.5 kuya ku-2%.
Umsebenzi we-salicylic acid
I-salicylic acid ingasetshenziswa njengezinto zokusetshenziswa kwemithi. Ukulungiselela i-aspirin, i-sodium salicylate, i-salicylamide, i-analgesic, i-phenyl salicylate, nezinye. Imboni yokudayaukulungiswa kwe-moxibustion ephuzi ehlanzekile, i-3GN ensundu eqondile, i-acid chrome ephuzi nokunye.Iphinde isetshenziswe njenge-rubber vulcanization retarder kanye nama-disinfectant preservatives

Ukusetshenziswa kwe-salicylic acid
1. I-salicylic acid okuyi-ortho hydroxy benzoic acid (o-hydroxybenzoic acid) iwuhlobo lweizinto zokwenziwa ezibalulekile ze-organic.Ekukhiqizeni izibulala-zinambuzane, isetshenziselwa ukwenza i-organic phosphorus pesticide Isocarbophos,i-isofenphos methyl intermediate isopropyl salicylate ne-Rodenticide warfarin, ibulala i-ether yamagundane i-4-hydroxy coumarin ephakathi; embonini yezemithi, i-salicylic acid yayisetshenziswa njenge ama-antiseptics, futhi njenge-intermediate ye-acetylsalicylic acid (aspirin) nezinye izidakamizwa; futhi i-impahla ebalulekile kadayi, izinongo, njengemboni yenjoloba .
2. Isetshenziswa kakhulu njengezinto zokusetshenziswa ze-aspirin feedstock kanye ne-pesticide aqueous amine andimikhiqizo ye-phosphorus, ingasetshenziswa futhi embonini kadayi, ukucwenga kanye ne-reagent yamakhemikhali, njll.
3. Isetshenziswa embonini yezemithi ye-antipyretic, analgesic, anti-inflammatory,izidakamizwa ze-diuretic, udayi wezimboni osetshenziselwa udayi oqondile we-azo kanye nodayi be-acid mordant, kodwa futhi nezinongo, njll.
4. Isetshenziswa njengenkomba eyinkimbinkimbi kanye ne-preservative.
5. Ukuqinisekiswa kwe-aluminium, i-boron, i-cerium, ithusi, insimbi, umthofu, i-manganese, i-mercury, i-nickel, isiliva,
titanium, tungsten, vanadium, sulfite, nitrate kanye nitrite. Ukunqunywa kwe-aluminium, ithusi, insimbi, i-thorium, i-titanium ne-uranium. Indlela ye-alkali kanye ne-iodometry titration standard. I-fluorescent inkomba. Inkomba ye-Complexometric.| Into | Inkomba |
