84-76-4 Usage
Description
Dinonyl phthalate, a phthalate derivative and organic extract contaminant, is found in drinking water and has been shown to activate the Nrf-2-mediated antioxidant response in human cell lines.
Uses
Used in Environmental and Health Research:
Dinonyl phthalate is used as a research subject for studying its impact on human health and the environment. Its presence in drinking water and its ability to activate the Nrf-2-mediated antioxidant response in human cell lines make it a significant focus for understanding potential health risks and developing strategies for water purification and contaminant removal.
Reactivity Profile
Dinonyl phthalate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Can generate electrostatic charges [Handling Chemicals Safely, 1980. p. 250].
Health Hazard
Moderately toxic by ingestion.
Check Digit Verification of cas no
The CAS Registry Mumber 84-76-4 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 84-76:
(4*8)+(3*4)+(2*7)+(1*6)=64
64 % 10 = 4
So 84-76-4 is a valid CAS Registry Number.

-
Paragraph 0020-0023; 0027, (2017/02/24)
The invention relates to a method for preparation of diester phthalate by o-xylene liquid-phase oxidation and esterification coupling. In the presence of a catalyst, air or oxygen is used as an oxygen source for preparation of the diester phthalate by o-xylene liquid-phase oxidation and esterification coupling. The method has the advantages of mild reaction conditions, safe operation, low raw material and energy consumption, high conversion rate and high selectivity and the like.
Process for producing carboxylic acid esters and catalysts therefor

, (2008/06/13)
A process for producing carboxylic acid esters by the following steps: a) preparation of a reaction mixture containing an alcohol and a carboxylic acid and/or a carboxylic anhydride and/or a carboxylic acid ester and or a partially esterified carboxylic acid, b) heating of this mixture to the suitable reaction temperature in the presence of a solid polysiloxane insoluble in the reaction medium and having sulphonic acid groups with intensive thorough mixing accompanied by continuous separation of the reaction water which forms, wherein the polysiloxane used as the catalyst in modified by treatment with a soluble aluminum, titanium or zirconium compound, and the spherical particles thereof have a diameter of 0.01 to 3 mm, a specific surface of 0.1 to 1200 m2 /g, a specific pore volume of 0.01 to 6.0 ml/g and a bulk density of 50 to 1000 g/l.
