Daim Ntawv Thov:
Ib qho ntawm kev siv tseem ceeb ntawm aniline yog nyob rau hauv kev tsim cov xim. Nws lub peev xwm los tsim cov xim sib xyaw thaum ua ke nrog lwm cov tshuaj ua rau nws zoo tagnrho rau kev tsim cov xim ci ntsa iab thiab kav ntev. Aniline dyes siv rau hauv ntau yam lag luam, suav nrog textiles, plastics, thiab tawv. Los ntawm kev siv aniline-based dyes, cov chaw tsim khoom tuaj yeem ua tiav ntau yam xim uas tiv taus kev ploj mus, kom ntseeg tau tias cov khoom khaws cia lawv qhov kev nyiam pom dhau sijhawm.
Tsis tas li ntawd xwb, aniline ua lub luag haujlwm tseem ceeb hauv kev tsim cov tshuaj thiab cov tshuaj. Raws li lub hauv paus tseem ceeb hauv kev tshuaj lom neeg organic, aniline ua haujlwm ua cov khoom siv pib rau kev tsim ntau yam tshuaj. Cov tuam txhab tshuaj siv cov aniline derivatives los tsim cov tshuaj rau ntau yam mob. Lub peev xwm los hloov kho cov qauv ntawm aniline tso cai rau cov kws tshawb fawb tsim cov tshuaj nrog cov txiaj ntsig kho mob xav tau.
Ntxiv mus, aniline pom daim ntawv thov hauv kev tsim cov resins. Cov resins yog qhov tseem ceeb hauv kev tsim cov yas, cov nplaum, thiab cov txheej txheem. Los ntawm kev koom ua ke aniline rau hauv cov qauv resin, cov chaw tsim khoom txhim kho lub zog, kev ruaj khov, thiab kev ywj pheej ntawm cov khoom kawg. Qhov no ua rau muaj peev xwm tsim cov khoom siv zoo uas tuaj yeem tiv taus cov xwm txheej nyuaj thiab muab lub neej ntev.
Aniline muaj ntau yam siv tau ntau tshaj li cov xim pleev, tshuaj, thiab cov resins. Nws kuj siv tau ua lub tshuab ua kom roj hmab vulcanization accelerator. Cov khoom siv roj hmab, xws li cov log tsheb thiab cov siv conveyor, xav tau vulcanization los txhim kho lawv lub zog thiab elasticity. Aniline pab ua kom cov txheej txheem vulcanization sai dua, ua rau cov roj hmab tsim tau zoo dua. Los ntawm kev siv aniline ua lub tshuab ua kom nrawm dua, cov chaw tsim khoom tuaj yeem txo lub sijhawm tsim khoom thiab txhim kho qhov zoo ntawm cov khoom siv roj hmab.
Ntxiv rau nws cov kev siv hauv kev lag luam, aniline kuj tseem siv tau ua cov xim dub nws tus kheej. Cov yam ntxwv no ua rau nws xav tau hauv ntau yam kev kos duab thiab kev muaj tswv yim. Cov kws kos duab thiab cov kws ua tes ua taw tuaj yeem siv aniline los tsim cov xim dub tob uas ntxiv qhov sib piv, qhov tob, thiab kev nplua nuj rau lawv cov khoom tsim. Nws cov xim ci ntsa iab thiab kev sib haum xeeb nrog ntau yam khoom siv sib txawv tso cai rau kev qhia tawm thiab kev tshawb nrhiav kos duab.
Ntxiv mus, cov aniline derivatives, xws li methyl orange, pom tias siv tau ua cov cim qhia hauv acid-base titrations. Cov cim qhia no yog qhov tseem ceeb hauv kev txiav txim siab qhov kawg ntawm kev sim titration, kom ntseeg tau tias muaj kev ntsuas tseeb. Methyl orange, muab los ntawm aniline, hloov xim thaum pH ntawm cov tshuaj mus txog qhov ntau yam tshwj xeeb. Qhov no tso cai rau cov kws tshawb fawb thiab cov kws tshuaj lom neeg saib xyuas thiab tshuaj xyuas cov tshuaj tiv thaiv uas tshwm sim thaum lub sijhawm titrations.

Kev ceev faj ua haujlwm:Kev ua haujlwm kaw, muab cov pa tawm hauv zos txaus. Kev ua haujlwm ua tshuab thiab tsis siv neeg li sai tau. Cov neeg ua haujlwm yuav tsum tau kawm tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm nruj me ntsis. Nws raug pom zoo kom tus neeg ua haujlwm hnav lub ntsej muag roj lim (ib nrab lub ntsej muag), tsom iav tiv thaiv kev nyab xeeb, khaub ncaws ua haujlwm tiv thaiv, thiab hnab looj tes roj hmab tiv taus roj. Khaws cia deb ntawm hluav taws thiab cua sov. Tsis txhob haus luam yeeb hauv chaw ua haujlwm. Siv cov tshuab cua thiab cov khoom siv uas tsis tawg.
