59129-79-2 Usage

Appearance

2'-anilino-6'-[ethyl(p-tolyl)amino]-3'-methylspiro[isobenzofuran-1(3H),9'-[9H]xanthene]-3-one is a white to off-white powder.

Uses

2'-anilino-6'-[ethyl(p-tolyl)amino]-3'-methylspiro[isobenzofuran-1(3H),9'-[9H]xanthene]-3-one is a hydrocarbon derivative and can be used as a thermal paper coupler, thermal ink, etc.

Check Digit Verification of cas no

The CAS Registry Mumber 59129-79-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,1,2 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 59129-79:
(7*5)+(6*9)+(5*1)+(4*2)+(3*9)+(2*7)+(1*9)=152
152 % 10 = 2
So 59129-79-2 is a valid CAS Registry Number.

A synthetic glimmer alkanes black the thermo-compression is sensitive coupler method

Paragraph 0044; 0045; 0046; 0052-0057, (2017/08/25)

The invention provides a method for synthesizing fluorane type black thermal-pressure sensitive color formers. The method, which takes benzophenone acid and 4-methoxy-2-methyl diphenyl amine as raw materials, comprises the following steps: adding benzophenone acid, 4-methoxy-2-methyl diphenyl amine and a catalyst into an organic solvent for reaction, and filtering the reaction liquid to obtain filtrate after the reaction is ended; adding water into the filtrate and regulating the pH of the filtrate to be greater than 10, and then heating and refluxing to remove a water phase and to obtain an organic phase; cooling and crystallizing the organic phase, and filtering to obtain the fluorane type color formers. The color formers prepared by the method comprise aryls which replace the alkyls in a conventional black color former, so that a conjugated system in the color former molecules is further increased, and the photon absorbing intensity of the color formers is increased. An efficient and recoverable a solid-acid catalyst is adopted, so that consumption of acid and alkalis in the preparation process is reduced, the discharge amount of waste acid and waste water is greatly reduced, the production cost is saved, and the color formers are more environmentally friendly.
