84-77-5 Usage
Chemical Properties
clear light yellow viscous liquid. soluble in alcohol, ether, acetone, insoluble in water.
Uses
Didecyl Phthalate is a primary plasticizer for vinyl resins and also shown to be compatible with polystyrene and cellulosics.
Application
Didecyl phthalate has low volatility, only a quarter of that of dioctyl phthalate (DOP), and has low migration and good resistance to extraction. It can be used as a plasticizer for vinyl resins and cellulose resins. It is also used as a stationary liquid for gas chromatography, with a maximum use temperature of 150 °C, and the solvent is acetone, chloroform or methanol. It can selectively retain and separate aromatic compounds, unsaturated compounds and various oxygen-containing compounds (alcohols, aldehydes, ketones and esters). etc.), halogenated hydrocarbons and hydrocarbon compounds below G.
Preparation
Didecyl phthalate is synthesized by esterification of phthalic anhydride and decyl alcohol. The production methods of phthalate plasticizers are common, see the production method of dioctyl phthalate (C24H38O4, [117-84-0]. In actual industrial products, there is no complete linear Didecyl phthalate is a mixture of branched chain esters, but the ratio of isomers is different.
Check Digit Verification of cas no
The CAS Registry Mumber 84-77-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84-77:
(4*8)+(3*4)+(2*7)+(1*7)=65
65 % 10 = 5
So 84-77-5 is a valid CAS Registry Number.

Preparation method of room-temperature phosphorescent benzoate compound
-
Paragraph 0157-0160, (2019/07/16)
The invention relates to a room-temperature phosphorescent benzoate compound. The benzoate compound is prepared by an efficient one-step method, and the prepared benzoate compound has obvious phosphorescence at room temperature, thereby broadening the application range of the benzoate compound. The product can be widely applied to phosphorescent materials.
