Usage

Uses

Different sources of media describe the Uses of 548-61-8 differently. You can refer to the following data:
1. tris(4-aminophenyl)methane is mainly used in the manufacture of poly isocyanate adhesive and polymer isocyanate adhesive is a rubber and metal or a non metal material is the best binder of rubber with various woven objects (natural or synthetic fiber) and leather adhesive is particularly suitable. Polymer isocyanate adhesive is a compound containing isocyanate group (- NCO) can interact with a variety of chemical groups (- Oh, - H, - NH2 or unsaturated substances), thereby the object firmly bonded together and adhesion is quite good, usually at or more than desire bonded non metal material strength. After bonding, the intrinsic bonding force can be maintained at high temperature and moisture, and it is welcomed by users.. Now widely used in aviation machinery, petrochemical, electronic machinery, transportation, construction, light industry and other departments.
2. 4,4'',4''''-Methanetriyltrianiline is an inhibitor of hepatitis C virus helicase. 4,4'',4''''-Methanetriyltrianiline has a carcinogenic activity and increases the incidence of tumors in the recticuloendothelial system of animals.

Design and synthesis of new nanosized C 3-symmetrical tricarboxylic acids: Key elongated ligands for the preparation of highly porous MOFs

The synthesis of two new C 3-symmetrical nanosized tricarboxylic acids bearing triphenylmethane cores and three imines linkages is presented. The new elongated tripods were designed to stabilise highly porous metal-organic frameworks (MOFs) and

LEUCO TRIPHENYLMETHANE COLORANTS AS BLUING AGENTS IN LAUNDRY CARE COMPOSITIONS

This application describes laundry care compositions that contain leuco colorants and their use in the laundering of textile articles. These types of colorants are provided in a stable, substantially colorless state and then may be transformed to an intense colored state upon exposure to certain physical or chemical changes such as, for example, exposure to oxygen, ion addition, exposure to light, and the like. The laundry care compositions containing the leuco colorants are designed to enhance the apparent or visually perceived whiteness of, or to impart a desired hue to, textile articles washed or otherwise treated with the laundry care composition.

Polythioureas: Main chain chiral polymers in hydride transfer hydrogenation

Chiral polythioureas have been synthesized and tested in asymmetric hydride transfer reduction of ketones with ruthenium. With polyurea 18, 70% ee was attained for acetophenone reduction; after filtration, it can be reused at least four times without any detectable loss of activity and only a slight decrease in selectivity. Various aryl alkyl ketones were reduced with the same system and up to 84% ee was measured with isopropyl phenyl ketone.
