Kev piav qhia:
NAPHTHENIC ACID yog ib yam kua xim tsaus uas muaj ntxhiab tsw phem. NAPHTHENIC ACID tsis yaj hauv dej. NAPHTHENIC ACID yuav kub hnyiab txawm hais tias NAPHTHENIC ACID yuav siv zog me ntsis los hlawv. Qhov txaus ntshai tseem ceeb yog qhov txaus ntshai rau ib puag ncig. Yuav tsum ua cov kauj ruam tam sim ntawd kom txo nws txoj kev kis mus rau ib puag ncig. Vim NAPHTHENIC ACID yog ib yam kua NAPHTHENIC ACID tuaj yeem nkag mus rau hauv av thiab ua rau cov dej hauv av thiab cov kwj deg nyob ze puas tsuaj. NAPHTHENIC ACID siv los ua cov tshuab ziab xim, cov tshuaj ntxuav tes, thiab cov kuab tshuaj.

Kev Siv
Lo lus naphthenic acid, raws li feem ntau siv hauv kev lag luam roj av, hais txog tag nrho cov carboxylic acids uas muaj nyob hauv cov roj av nyoos.
Naphthenic acid feem ntau siv rau hauv kev tsim cov hlau naphthenates uas muaj txiaj ntsig xws li tooj liab naphthenate, uas yog cov tshuaj tiv thaiv ntoo; titanium naphthenate, uas yog cov ua ntej rau kev npaj cov zaj duab xis nyias titanium oxide thiab cov av tsis tshua muaj naphthenate, uas yog cov roj nplua nyeem ntxiv. Nws kuj tseem tuaj yeem siv rau hauv kev tsim cov kua naphthenic acid ionic uas lwj tau.
