Lactic Acid
Lactic acid, nrog cov tshuaj noj cov mis nyuj c₃h₆o₃, yog xim tsis muaj xim, dej-soluble organic acid uas tshwm sim hauv ntau yam kev ua leeg nqaij cov leeg. Nws muaj cov yam ntxwv qab zib qaub, feem ntau cuam tshuam nrog cov khoom noj mis nyuj thiab cov khoom noj fermented. Lactic acid muaj nyob rau hauv ob lub optical isomers: L-lactic acid (lub zog ua haujlwm biologically) thiab d-lactic acid.
Nyob rau hauv nws cov ntaub ntawv ntshiab, lactic acid yog cov kua ua kua uas tsis zoo nrog dej, ethanol, thiab ether. Nws muaj lub ntsiab lus melting ntawm ib ncig 18,5 degree (65.3 degree f) thiab lub bub point ntawm 122 degree (252 degree f) ntawm 12 hli. Lactic acid yog cov kua qaub tsis muaj zog, nrog pka ntawm kwv yees li ntawm 3.}}}}}} Cov kev daws teeb meem kom tso hydrogen ions (h⁺). Qhov sib xyaw ua ke yog paub rau nws lub peev xwm los ua cov ntsev, xws li lactates, thaum reacting nrog cov hauv paus.
Raws li alpha-hydroxy acid (AHA), lactic acid feem ntau yog siv hauv cov khoom lag luam tawv ncauj vim nws cov khoom exfoliating. Nws tseem muaj cov ntawv thov tseem ceeb hauv kev tsim cov khoom lag luam biodegradable plastics, khoom noj kom txuag tau, thiab tshuaj.

Lactic acid muaj ntau cov kev siv hauv kev lag luam ntau yam. Hauv kev lag luam khoom noj khoom haus, nws yog siv los ua cov tshuaj tiv thaiv, acidulant, thiab flavoring tus neeg sawv cev hauv cov khoom lag luam zoo li cov mis nyuj, dej haus, thiab pickles. Hauv cov tshuaj pleev ib ce thiab tawv nqaij, nws ua haujlwm ua ib qho kev hloov pauv thiab cov dej noo vim nws muaj peev xwm los txhawb cov tawv nqaij cell tig. Lactic acid kuj tseem siv tau ntawm cov khoom lag luam biodegradable plastics, tshwj xeeb yog cov acid acid (PLA), uas yog kev hloov kho hauv eco-based plastics. Ib qho ntxiv, nws yog kev koom tes hauv cov tshuaj yeeb yaj kiab, thiab hauv kev lag luam textile, nws yog siv rau zas thiab xov ntaub.
