PropanoI acid yog paub txog nws cov volatility thiab muaj ntxhiab tsw zoo, ua rau nws yooj yim los xyuas txawm tias tsis tshua muaj ntau. Nws tseem ua cov khoom pov tseg cov carboxylic acid kev coj, koom nrog kev tawm tsam zoo li Esterification thiab hydrogenation.
Cov yam ntxwv solubility
Propanoch acid yog soluble heev hauv polar kuab tshuaj li dej, ethananol, thiab ether. Nyob rau hauv chav tsev kub, nws tuaj yeem sib tov nrog dej vim tias muaj nws cov pab pawg carboxyl, uas cov ntaub ntawv hydrogen bonds nrog dej lwg me me. Cov xeeb ceem no yog qhov tseem ceeb rau kev siv hauv:
- Kev lag luam khoom noj khoom haus: qhov uas nws xav kom yaj thiab muaj cov khoom noj ntxiv.
- Kws muag tshuaj: kom paub tseeb tias faib tawm hauv cov kua ua kua.
Nws yog tsawg dua soluble hauv tsis - polar cov kuab tshuaj zoo li hydrocarbons tab sis tseem tuaj yeem cuam tshuam vim nws txoj kab ntev.
Cov Khoom Siv Acidity (PKA)
PKA Tus Nqi: 4.87
Tus nqi no qhia tau tias cov tshuaj pleev cov prodanoic yog ib nrab - Lub zog carboxylic acid. Nws tuaj yeem ua cov kab mob protons (h⁺ ions) yooj yim hauv cov kev daws teeb meem aqueous, ua rau nws tsim nyog cov kev ntsuas ntawm cov acidity acidity yog qhov yuav tsum tau ua. Nyob rau hauv cov ntsiab lus, propanoic acid cov acidity yog siv rau:
- Kev khaws cia: Txo cov pH hauv cov khoom noj khoom noj kom ua rau muaj kev loj hlob microbial.
- Tshuaj lom neeg cov tshuaj tiv thaiv: ua yeeb yam raws li cov neeg ua haujlwm proton hauv cov synthic.
- Cov kev daws teeb meem tsis tau: Siv cov qauv uas xav tau PHEM rau qib.
Cov ntawv thov ntawm propionic acid
- Cov Ntawv Thov:
Siv los ua tus neeg saib xyuas esterification, hnyav rau cellulose nitrate, yasizer, tshuaj lom neeg cov khoom noj, thiab hauv cov qauv khoom noj khoom haus.
- Cov Khoom Noj Khoom Noj Txhaum Cai
Cov tshuaj antifungal thiab kev ua kom muaj kev cuam tshuam ntawm propionic acid yog zoo dua rau cov ntawm benzoic acid ntawm pH qhov tseem ceeb hauv qab 6.0, thiab nws cov nqi qis dua li cov kua qaub acid. Qhov no ua rau nws yog ib qho khoom noj uas zoo tshaj plaws ua noj, nrog kev ua lag luam loj hauv Suav teb.
- Tshuaj tua kab
Hauv kev siv tshuaj tua kab,Proflionic acidPuas yog siv los tsim cov propionamide, ib nrab rau kev tsim qee yam tshuaj tua kab. Raws li Tuam Tshoj cov tshuaj tua kab kev siv tshuaj tua kab, cov tshuaj tua kab yog cov khoom tseem ceeb rau kev loj hlob tom ntej.
- Tus ntxhiab
Nyob rau hauv kev lag luam fragrance, propionic acid yog siv los tsim isopentyl propionate, Geryl Proxionate, uas yog siv ntxiv rau hauv cov zaub mov, cov tshuaj pleev ib ce, thiab tshuaj ntxuav cov ntxhiab tsw.
- Kws Tshuaj
Nyob rau hauv lub chaw muag tshuaj, loj derivatives ntawm propionic acid suav nrog cov vitamin B6, Napbroxen, thiab Neeb. Prodionic acid kuj tseem ceeb rau kev kho mob rau cov tawv nqaij ntawm cov tawv nqaij, thiab tuaj yeem siv hauv kev sib xyaw ua ke nrog zinc undecylenate thiab lwm yam khoom xyaw rau kev npaj sab nraud.
