2-[4-(Dibutylamino)-2-hydroxybenzoyl]benzoic acid, tseem hu ua BBA, yog hmoov crystalline daj daj.
1. Cov qauv tshuaj ruaj khov nrog kev ruaj khov thermal siab, melting point ntawm 190–193 ° C, tsim nyog rau cov txheej txheem synthesis kub siab;
2. Kev huv siab, cov ntsiab lus tsis muaj kuab paug tsawg, cov dej noo tsawg (poob thaum ziab ≤0.2%), cov khoom zoo sib xws los ntawm ib pawg;
3. Muaj cov carboxylic acid functional group, yooj yim rau kev ua esterification thiab condensation reactions; zoo heev reactivity ua qhov tseem ceeb synthetic intermediate;
4. Kev hloov pauv tsawg nyob rau hauv cov xwm txheej ua haujlwm ib txwm muaj, kev ruaj khov zoo ntawm kev khaws cia; kev khaws cia kaw rau hauv qhov chaw txias thiab qhuav tiv thaiv kev puas tsuaj;
5. Insoluble hauv dej, soluble hauv cov organic solvents xws li cawv, esters thiab aromatic solvents.

BBA (CAS 54574-82-2) yog ib qho tseem ceeb rau cov xim leuco (cov xim formers) rau daim ntawv thermal thiab daim ntawv rhiab siab.
1. Kev Lag Luam Thermal Rhiab / Thermal Ntawv
Nws yog cov khoom siv tseem ceeb rau kev tsim cov xim dub thermal leuco, siv dav rau daim ntawv txais nyiaj thermal, daim ntawv lo, daim pib lottery, daim ntawv facsimile, daim ntawv them nqi taxi, thiab daim ntawv luam ntawv POS. Cov xim tiav lawm muaj xim luam tawm meej, xim sai sai, tiv taus lub teeb zoo heev thiab tiv thaiv kev ploj xim.
2. Daim Ntawv Carbonless Uas Muaj Kev Nyuaj Siab
Siv rau kev tsim cov tshuaj chromogenic rau cov ntawv luam carbonless, siv tau rau cov ntawv xa khoom lag luam, cov ntaub ntawv cog lus, cov ntawv ntau txheej.
3. Tshuaj Zoo & Xim Nruab Nrab
Siv rau hauv kev tsim cov amino-substituted benzophenone derivatives, organic colorants, optical functional materials.
