2. Dicyclohexyl Phthalate is a phthalate ester used as a plasticizer as well as being present in cosmetic products. Dicyclohexyl Phthalate that is a weak drug-type inducer of hepatic xenobiotic metabolism.
3. DCHP modified multi-walled carbon nanotubes (MWCNTs) may be used to functionalize screen printed electrodes in biosensor based applications. It may also be used as a reference standard for the determination of dicyclohexyl phthalate in aquatic matrices by ultra-high performance liquid chromatography coupled to hybrid Q-orbitrap mass spectrometry(UHPLC-HRMS).
General Description
White granular solid with an aromatic odor. Water insoluble.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Dicyclohexyl 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. Dicyclohexyl phthalate reacts with oxidizers. Dicyclohexyl phthalate hydrolyzes under acid and basic conditions.
Health Hazard
ACUTE/CHRONIC HAZARDS: Dicyclohexyl phthalate may cause irritation on contact.
Fire Hazard
Dicyclohexyl phthalate is combustible.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 84-61-7 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, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 84-61:
(4*8)+(3*4)+(2*6)+(1*1)=57
57 % 10 = 7
So 84-61-7 is a valid CAS Registry Number.

A liquid phase oxidation of O-xylene with esterification coupling preparation of phthalic acid diester method
-
Paragraph 0020-0023; 0026, (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.
Efficient synthesis of symmetrical phthalate and maleate diesters using phosphinite ionic liquids
Valizadeh,Khalili
, p. 529 - 534 (2013/02/22)
Symmetrical dialkyl phthalates and maleates were synthesized using phosphinite ionic liquid as a catalyst and reaction medium. The results indicated that phosphinite ionic liquid shows better catalytic and reusable performance without using any acid or base catalyst. Under the optimum conditions, using 1-methyl-3-(4-phosphinitebutyl) imidazolium chloride as catalyst, the conversion of phthalic and maleic anhydrides to the corresponding diesters of primary and secondary alcohols was occurred in 72-85% yields. The diesters of tertiary alcohols and phenols could not be prepared by this method. A kind of widely used plasticizer, dioctyl phthalate, was prepared in good yield under these conditions. The ionic liquid could be reused three times after easy separation from the products without any disposal. Iranian Chemical Society 2012.
Synthesis, characterization and catalytic properties of SAPO-11, -31 and -41 molecular sieves
Venkatathri,Srivastava
, p. 1039 - 1043 (2007/10/03)
Medium pore molecular sieves, SAPO-11, SAPO-31 and SAPO-41, have been synthesized using di-n-propylamine and diethylamine as the organic template. They have been characterized by various methods such as elemental analysis, X-ray powder diffraction, solid state MAS NMR spectroscopy, and FT-IR spectroscopy in the framework and hydroxyl regions. Catalytic activities of these materials in the esterification of phthalic anhydride with different alcohols have been studied. The catalytic activity of these material is in the order: SAPO-41> SAPO-11> SAPO-31.
