I-2-[4-(Dibutylamino)-2-hydroxybenzoyl]benzoic acid, ekwaziwa ngokuba yi-BBA, yipowder yekristale etyheli ekhanyayo.
1. Ulwakhiwo lwekhemikhali oluzinzileyo olunozinzo oluphezulu lobushushu, iqondo lokunyibilika kwi-190–193 °C, olufanele inkqubo yokwenziwa kobushushu obuphezulu;
2. Ubunyulu obuphezulu, umxholo wokungcola ophantsi, ukufuma okuphantsi (ukulahleka xa komiswa ≤0.2%), ibhetshi yomgangatho ohambelanayo ngebhetshi nganye;
3. Iqulethe iqela elisebenzayo le-carboxylic acid, kulula ukuqhuba i-esterification kunye ne-condensation reactions; i-reactivity egqwesileyo njenge-key synthetic intermediate;
4. Ukuguquguquka okuphantsi phantsi kweemeko eziqhelekileyo zokucubungula, uzinzo oluhle lokugcina; ukugcinwa okuvaliweyo kwindawo epholileyo neyomileyo kuthintela ukonakala;
5. Ayinyibiliki emanzini, inyibilika kwizinyibilikisi eziqhelekileyo zendalo ezifana neealcohols, ii-esters kunye nezinyibilikisi ezinuka kamnandi.

I-BBA (CAS 54574-82-2) sisixhobo esiphambili sedayi ze-leuco (izinto ezibumba imibala) zephepha elishushu kunye nephepha elinoxinzelelo.
1. Iidayi Ezinobuthathaka Kubushushu Obuphezulu / Ushishino Lwephepha Elinobushushu Obuphezulu
Yinto ebalulekileyo ekuveliseni iidayi ze-leuco ezimnyama ezishushu, ezisetyenziswa kakhulu kwiphepha lerisithi ezishushu, iphepha leelebheli, amatikiti elotho, iphepha le-facsimile, iphepha leebhili zeteksi, iphepha lokuprinta le-POS. Idayi egqityiweyo inombala ocacileyo wokuprinta, isantya esihle sokuphucula umbala, ukumelana nokukhanya okugqwesileyo kunye nokusebenza okuchasene nokufiphala.
2. Iphepha Elingenakhabhoni Elinoxinzelelo Olunzima
Isetyenziselwa ukuvelisa iikhompawundi ze-chromogenic zephepha lokukopa elingenakhabhoni, ezisebenza kwii-invoyisi zorhwebo, amaxwebhu esivumelwano, iifom ezineeleya ezininzi.
3. I-Fine Chemical & Daye Intermediate
Isetyenziswa ekuhlanganiseni ezinye izinto ezithathwe kwi-amino-substituted benzophenone, izinto ezinombala eziphilayo, kunye nezinto ezisebenzayo ezibonakalayo.
