CAS 112-38-9 Undecylenic Acid

1. Taw qhia

Undecenoic acid yog cov kua daj mus rau daj, yog tias tsis xav tau, nws yuav dhau los ua cov kua mis dawb crystalline; nws yog tsw ntxhiab tsw. Nws tuaj yeem ua rau miscible arbitrarily nrog ethanol, chloroform, ether, fatty oil lossis volatile roj, thiab yuav luag insoluble hauv dej. Nws yog siv los kho cov tawv nqaij thiab mucosal fungi, xws li tinea capitis, tinea cruris, tinea pedis thiab lwm yam kab mob ntawm daim tawv nqaij thiab fungal vaginitis. Cov nyhuv curative ntawm tinea pedis yog qhov zoo tshaj plaws. Nws kuj tuaj yeem siv rau hauv kev tsim cov zinc 10-undecenoate, synthesis ntawm -undecenolide spices, nylon thiab lwm yam khoom.

2. Muaj nuj nqi

2.1 Kev lag luam tshuaj: Undecenoic acid yog ib qho tseem ceeb raw khoom rau kev sib txuas ntawm cov txuj lom, xws li txuj lom -undecanolide (tseem hu ua txiv duaj aldehyde), polycyclic pentadecanolide, muscone, nonanal thiab nonyl cawv, thiab lwm yam. Nws kuj yog ib qho tshuaj antifungal rau kev kho mob ntawm daim tawv nqaij mycosis (kev npaj ntawm beriberi, thiab lwm yam).

2.2 Kev lag luam tshuaj pleev ib ce: Feem ntau siv rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej, xws li cov tshuaj pleev ib ce, tshuaj zawv plaub hau, tshuaj kho mob, thiab lwm yam, nrog rau cov tshuaj tua kab mob thiab tshuaj tua kab mob.

3.3 Muaj: Hauv kev lag luam, undecenoic acid tuaj yeem siv los ua ib qho ntxiv, xws li tus neeg sawv cev sib txuas hauv polymers thiab txheej txheej, lossis hauv kev ua liaj ua teb rau kev npaj cov fungicides.

2.4 Spice: Nws yog qee zaum siv los ua ib qho ntawm cov khoom xyaw ntawm cov txuj lom thiab seasonings, muab cov khoom tshwj xeeb tsw thiab tsw.

3. Daim ntawv thov

Undecenoic acid yog dav siv hauv tshuaj, tshuaj pleev ib ce, kev lag luam thiab zaub mov kev lag luam.
