Adipic Acid yog dab tsi?
Adipic acid yog ib qho organic compound uas yog ib qho tseem ceeb heev raws li ib tug precursor rau zus tau tej cov nylon. Cov tshuaj formula rau cov molecule no yog (CH2)4(COOH)2Qhov no feem ntau yog cov khoom siv hluavtaws, tab sis nws tuaj yeem tshwm sim tsis tshua muaj tshwm sim. Thaum tsim muaj kev lag luam, nws zoo li cov muaju dawb, thiab nws tsis muaj ntxhiab.
Daim duab 01: Cov qauv ntawm Adipic Acid
Thaum xav txog kev tsim cov adipic acid, peb tuaj yeem tsim nws los ntawm kev sib xyaw ntawm cyclohexanone thiab cyclohexanol. Lub sij hawm kev lag luam rau qhov sib tov yog "KA roj". Nws hais tias qhov sib tov no yog Ketone-Cawv roj. Adipic acid tsim los ntawm oxidation ntawm KA roj nrog nitric acid. Txawm li cas los xij, muaj qee txoj hauv kev rau kev tsim khoom, xws li oxidative cleavage ntawm cyclohexene nyob rau hauv muaj hydrogen peroxide.
Kev siv ntau tshaj plaws ntawm adipic acid yog ua ntej rau kev tsim cov khoom siv nylon polymer. Qhov no yog cov tshuaj tiv thaiv polycondensation uas tshwm sim nyob rau hauv lub xub ntiag ntawm hexamethylene diamine. Tsis tas li ntawd, adipic acid yog ib qho tseem ceeb raws li ib tug matrix compound rau cov tshuaj nyob rau hauv cov tshuaj rau cov pH ywj siab tso tawm ntawm cov tshuaj. Ntxiv mus, adipic acid yog ib qho tseem ceeb raws li cov khoom noj ntxiv rau tsw thiab ua ib qho kev pab gelling.
YSalicylic Acid yog dab tsi?
Salicylic acid yog ib qho organic compound, thiab nws yog ib qho tseem ceeb ua tshuaj uas pab tshem tawm txheej txheej ntawm daim tawv nqaij. Nws yog xim tsis muaj xim rau dawb crystalline khoom uas tsis muaj ntxhiab tsw. Cov tshuaj formula ntawm salicylic acid yog C7H6O3. Cov molar mass ntawm no compound yog 138.12 g / mol. Lub melting point ntawm salicylic acid crystals yog 158.6 ° C thiab, nws decomposes ntawm 200 ° C. Cov muaju no tuaj yeem ua rau sublimation ntawm 76 ° C (sublimation yog hloov dua siab tshiab ntawm cov khoom ncaj qha mus rau nws cov theem vapor yam tsis tau mus txog theem ua kua). Lub npe IUPAC ntawm salicylic acid yog 2-Hydroxybenzoic acid.
Daim duab 02: Cov qauv ntawm Salicylic Acid
Salicylic acid yog siv los ua tshuaj. Nws yog siv los kho warts, dandruff, pob txuv thiab lwm yam kab mob ntawm daim tawv nqaij vim nws muaj peev xwm tshem tawm txheej txheej ntawm daim tawv nqaij. Yog li ntawd, salicylic acid yog cov khoom siv tseem ceeb hauv kev tsim cov khoom tu tawv nqaij; Piv txwv li, nws yog siv nyob rau hauv ib co tshuaj zawv plaub hau los kho dandruff. Tsis tas li ntawd, nws yog siv rau hauv kev tsim Pepto-Bismol, tshuaj siv los kho cov kab mob plab hnyuv. Salicylic acid kuj tseem siv los ua zaub mov noj.
Qhov txawv ntawm Adipic Acid thiab Salicylic Acid yog dab tsi?
Adipic acid yog ib qho organic compound uas yog ib qho tseem ceeb heev raws li ib tug precursor rau zus tau tej cov nylon. Salicylic acid yog ib qho organic compound, thiab nws muaj txiaj ntsig zoo li cov tshuaj uas pab tshem tawm txheej txheej ntawm daim tawv nqaij. Qhov sib txawv tseem ceeb ntawm adipic acid thiab salicylic acid yog tias adipic acid muaj ob pawg carboxyl acid, hos salicylic acid muaj ib pawg carboxyl acid ib molecule.
Hauv qab infographic tabulates qhov sib txawv ntawm adipic acid thiab salicylic acid.
Summary – Adipic Acid vs Salicylic Acid
