2390-60-5 Usage
Chemical Properties
Bright brown powder
Preparation
Bis(4-(diethylamino)phenyl)methanone and N-Ethylnaphthalen-1-amine in toluene in different amine chlorine presence of phosphorus condensation.
Properties and Applications
colourful red blue light. Flash brown cream content. Slightly soluble in cold water, soluble in hot water for blue, easily soluble in ethanol to blue. The strong sulfuric acid is palm in light yellow, diluted red for yellow; In nitric acid for olive green. The dye solution to join sodium hydroxide for red brown. The thing in cotton dyeing, drop 10% of sulfuric acid into a light yellow brown; Drops of 10% sodium hydroxide solution become red light yellow; Drop acid solution red yellow ferrie sulfate-potassium thiosulfate change. Used for silk, wool, cotton cloth tannins mordant dyeing of dyeing, also can be used in the manufacture of oil, carbon, ball pen wax paper, bamboo and wood light color. Also used in the manufacture of color pigments and solvent dye deposit.

Check Digit Verification of cas no
The CAS Registry Mumber 2390-60-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2390-60:
(6*2)+(5*3)+(4*9)+(3*0)+(2*6)+(1*0)=75
75 % 10 = 5
So 2390-60-5 is a valid CAS Registry Number.

Method for preparing triarylmethane compounds and application thereof
-
Paragraph 0037-0039, (2019/11/13)
The invention discloses a method for preparing a triarylmethane dye. 4,4'-N,N-disubstituted aminodiphenylmethane (bass) and aromatic amines or substituted aromatic amines, phenols or substituted phenols are dissolved in a solvent, metal complexes and tetrachlorobenzoquinone are used as catalysts and oxygen is used as oxidant, the mixture reacts for 5-8 hours at acid conditions and a certain temperature, so that the product triarylmethane dye is obtained in one step, and the commercialized product is obtained through further treatment, so as to meet the application requirement in different fields. The method is simple and safe, and has high yield and less three-wastes.
Carbenium ion-carbinol equilibration for basic triarylmethane dyes: Relative reactivities of dyes in aq. solutions
Gupta, Susanta K. Sen,Arvind, Udai
, p. 998 - 1000 (2007/10/02)
Equilibria and kinetics of carbenium ion-to-carbinol base reactions for a set of selected basic triarylmethane dyes in aq. buffer solutions of low ionic strength have been measured spectrophotometrically.Relative reactivities of the dyes towards nucleophilic attack by hydroxide ion, on the basis of both equilibrium constant and forward rate constant of the reaction, have been found to follow the same order: malachite green (MG)> brillant green (BG)>> Victoria pure blue BO(VB)> methyl violet (MV) = crystal violet (CV)> ethyl vioet (EV).A fairly good correlation between elec trophilicities of the dyes and ?R+ parameters of their 4-alkylamino substituents has been obtained
