Basic Info

Model No.: 29512-49-0

Product Description

7-Anilino-3-diethylamino-6-methyl fluoran ( TF-BL1) CAS Number is 29512-49-0, also known as TF-BL1, hot (pressure) sensitive black TF-BL1, one day black, referred to as ODB-1. Molecular formula with C31H29N2O3 ,Molecular weight with 477.57, the appearance of white to fluorescent powder, aroma. It can be used as a hot (pressure) sensitive paper coupler for the production of hot (pressure) sensitive paper in the paper industry. TF-BL1 CAS Number 29512-49-0 can also be used to make a color card for rapid determination of ambient humidity. The specific steps are as follows: (1) Weigh 1.01g of pressure-sensitive black TF-BL1 and 0.0500g of tin tetrachloride, grind for 20 minutes, and add 1.5mL ethanol to completely dissolve, and then add 0.20mL 5mol / L H3PO4, stir to obtain a mixture;
(2) The mixture prepared in the step (1) is evenly spread on a circular plastic card, and naturally dried to form a color developing card. When the relative humidity is 20%-40%, the color card displays red. When the relative humidity is 40%-60%, the color card displays green. When the relative humidity is 60%-100%, the color card displays black.
