Qhov sib txawv tseem ceeb ntawm benzoyl peroxide thiab salicylic acid yog tias benzoyl peroxide belongs rau tsev neeg peroxide whereas salicylic acid belongs rau carboxylic acid tsev neeg.
Muaj ntau cov organic molecules uas muaj txiaj ntsig zoo rau tib neeg. Benzoyl peroxide thiab salicylic acid yog ob yam tshuaj uas siv los kho pob txuv. Ob leeg yog cov neeg ua haujlwm zoo rau kev tawm tsam pob txuv, tab sis nyob ntawm hom tawv nqaij, cov tshuaj tiv thaiv yuav txawv.
Benzoyl Peroxide yog dab tsi?
Benzoyl peroxide yog cov organic molecule nrog cov peroxide txuas. Nws muaj ob pawg benzoyl txuas nrog peroxide txuas. Nws cov mis molecular yog [C6H5C(O) 2O 2. Cov qauv ntawm cov molecule no yog raws li nram no.
Benzoyl peroxide yog cov khoom tsis muaj xim, thiab cov molar loj yog 242.23 g mol -1 Nws tuaj yeem yaj me ntsis hauv dej, tab sis yooj yim yaj hauv cov kuab tshuaj organic. Benzoyl peroxide tuaj yeem npaj los ntawm kev kho hydrogen peroxide nrog benzoyl chloride lossis kho benzoyl chloride nrog barium peroxide.
Benzoyl peroxide muaj txiaj ntsig zoo hauv tshuaj, tshwj xeeb tshaj yog kev kho pob txuv. Thaum nws nyob rau ntawm daim tawv nqaij, nws tawg mus rau hauv benzoic acid thiab oxygen. Benzoyl peroxide tsis muaj tshuaj lom. Nws kuj tseem tuaj yeem siv los ua tus pib radical hauv cov tshuaj tiv thaiv polymerization. Raws li lwm yam peroxide, qhov no kuj muaj cov tshuaj dawb huv. Nws yog siv rau hauv cov plaub hau dyeing, hniav ntxuav hniav dawb cov ntaub ntawv thiab lwm yam. Tsis tas li ntawd nws yuav siv tau raws li ib tug antiseptic.
YSalicylic Acid yog dab tsi?
Salicylic acid yog ib lub npe siv los hais txog monohydroxybenzoic acid. Nws yog ib qho tshuaj tsw qab uas ib pawg carboxylic txuas nrog phenol. Rhw OH pawg yog nyob rau ntawm txoj hauj lwm ortho rau pawg carboxyl. Hauv IUPAC nomenclature, nws yog lub npe hu ua 2-hydroxybenzenecarboxylic acid. Nws muaj cov qauv hauv qab no:
Salicylic acid yog crystalline khoom, thiab nws tsis muaj xim. Cov tshuaj no tau muab cais ua ntej los ntawm cov tawv ntoo ntawm tsob ntoo willow; Yog li nws tau txais lub npe los ntawm Latin lo lus salix, uas yog siv los qhia willow ntoo. Molar mass ntawm salicylic acid yog 138.12 g mol-1 Nws melting point yog 432 K, thiab nws boiling point yog 484 K. salicylic acid yog soluble nyob rau hauv dej.
Aspirin muaj cov qauv zoo ib yam li salicylic acid. Aspirin tuaj yeem tsim los ntawm esterification ntawm phenolic hydroxyl pawg ntawm salicylic acid nrog acetyl pawg los ntawm acetyl chloride. Salicylic acid yog cov tshuaj hormones cog. Nws muaj lub luag haujlwm ntawm kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag. Tsis tas li ntawd nws pab nrog photosynthesis, transpiration, ion uptake thiab thauj hauv cov nroj tsuag. Nyob rau hauv cov xwm, nws yog synthesized nyob rau hauv cov nroj tsuag los ntawm cov amino acid phenylalanine.
Salicylic acid yog siv rau kev siv tshuaj thiab tshuaj pleev ib ce. Tshwj xeeb tshaj yog salicylic acid yog siv los kho pob txuv cov tawv nqaij kom txo cov pob txuv thiab pob txuv. Nws yog cov khoom xyaw hauv cov tshuaj zawv plaub hau siv los kho dandruff. Salicylic acid kuj yog siv los ua tshuaj, kom txo tau kub taub hau thiab yooj yim mob thiab mob. Nws tseem yog ib qho tseem ceeb micronutrient xav tau rau tib neeg. Txiv hmab txiv ntoo thiab zaub xws li hnub, raisins, blueberries, guavas, txiv lws suav, thiab nceb muaj salicylic acid. Tsis tsuas yog salicylic acid xwb, tab sis nws cov derivatives kuj tseem siv tau rau ntau txoj kev.
Qhov txawv ntawm Benzoyl Peroxide thiab Salicylic Acid yog dab tsi?
Qhov sib txawv tseem ceeb ntawm benzoyl peroxide thiab salicylic acid yog tias benzoyl peroxide belongs rau tsev neeg peroxide whereas salicylic acid belongs rau carboxylic acid tsev neeg. Ntxiv mus, benzyl peroxide muaj ob lub nplhaib benzene, thaum salicylic acid tsuas muaj ib lub nplhaib benzene xwb. Ntxiv mus, salicylic acid yaj hauv dej zoo piv rau benzoyl peroxide. Piv rau salicylic acid, benzoyl peroxide tuaj yeem ua rau khaus rau qee hom tawv nqaij.
Summary - Benzoyl Peroxide vs Salicylic Acid
Benzoyl peroxide thiab salicylic acid yog ob yam tshuaj uas siv los kho pob txuv. Qhov sib txawv tseem ceeb ntawm benzoyl peroxide thiab salicylic acid yog tias benzoyl peroxide belongs rau tsev neeg peroxide whereas salicylic acid belongs rau carboxylic acid tsev neeg.
