meta-phosphoricacid CAS: 10343-62-1

Meta-phosphoric acid ua haujlwm rau ntau lub hom phiaj thoob plaws ntau yam lag luam vim nws cov khoom siv tshuaj lom neeg tshwj xeeb. Hauv kev tsim cov organic, nws ua haujlwm ua tus neeg sawv cev dehydrating muaj zog, pab txhawb kev tshem tawm cov dej molecules los ntawm cov tshuaj sib xyaw ua ke los tsav cov kev hloov pauv tshuaj tseem ceeb. Lub peev xwm dehydration no yog qhov tseem ceeb hauv kev tsim cov tshuaj intermediates, cov tshuaj tsw qab, thiab cov tshuaj tshwj xeeb. Ntxiv mus, meta-phosphoric acid pom kev siv dav hauv kev lag luam polymer rau kev tsim cov polymers thiab resins ua tau zoo. Nws cov khoom condensing ua rau muaj kev sib txuas molecular muaj zog, pab txhawb rau kev sib txuas thiab polymerization cov txheej txheem uas ua rau kev txhim kho cov ntaub ntawv siab heev nrog cov khoom siv kho tshuab thiab thermal zoo dua. Ntxiv mus, cov tshuaj no yog siv rau hauv kev tsim cov nplaim taws retardants thiab additives rau cov txheej txheem tiv thaiv hluav taws. Nws lub peev xwm los txhawb kev tsim char thiab inhibit combustion ua rau nws yog ib qho khoom xyaw tseem ceeb hauv cov ntaub ntawv tsim los ua kom tau raws li cov qauv kev nyab xeeb hluav taws hauv kev tsim kho, tsheb, thiab kev siv hluav taws xob. Ntxiv mus, meta-phosphoric acid yog siv ua catalyst hauv qee cov tshuaj tiv thaiv organic, tshwj xeeb tshaj yog hauv kev tsim cov tshuaj tshwj xeeb thiab cov organic compounds zoo. Nws cov kua qaub ua rau muaj kev hloov pauv tseem ceeb, xws li esterifications, amidations, thiab cyclizations, ua rau muaj kev tsim cov tshuaj lom neeg muaj txiaj ntsig zoo. Hauv kev lag luam khoom noj thiab dej haus, meta-phosphoric acid ua lub luag haujlwm tseem ceeb ua cov khoom noj khoom haus ntxiv thiab tshuaj tiv thaiv. Nws yog siv rau kev tswj pH, kev kho acidity, thiab ua tus stabilizer hauv ntau yam khoom noj, suav nrog dej haus, jams, jellies, thiab cov khoom noj hauv kaus poom. Nws lub peev xwm los tiv thaiv kev loj hlob ntawm cov kab mob thiab tswj cov khoom ruaj khov pab txhawb rau nws daim ntawv thov dav hauv kev lag luam khoom noj. Zuag qhia tag nrho, kev siv ntau yam ntawm meta-phosphoric acid qhia txog nws qhov tseem ceeb ua cov tshuaj reagent ntau yam hauv kev tsim cov organic, polymerization, nplaim taws retardancy, catalysis, thiab kev khaws cia khoom noj. Nws cov khoom tshwj xeeb dehydrating thiab condensing, ua ke nrog nws cov kua qaub muaj zog, ua rau nws yog ib qho tseem ceeb hauv ntau cov txheej txheem kev lag luam, pab txhawb rau kev nce qib ntawm ntau yam kev lag luam thiab kev txhim kho cov ntaub ntawv tshwj xeeb thiab cov tshuaj sib xyaw.
