4285-59-0

Propane, 2,2-ethylidenebis(oxy)bis-, also known as 2,2'-oxybispropane or simply dipropylene glycol (DPG), is a colorless, odorless, and viscous liquid with the chemical formula C6H14O3. It is a diol, meaning it contains two hydroxyl groups, and is a derivative of propane with two ethylene oxide units bridging the two propane molecules. DPG is widely used as a solvent, a humectant in cosmetics, a plasticizer, and a component in the production of polyurethane foams. It is also used as a heat transfer fluid in various industrial applications due to its high boiling point and low toxicity. The compound is generally considered safe, but it can cause mild skin and eye irritation upon direct contact.

Check Digit Verification of cas no

The CAS Registry Mumber 4285-59-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,8 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4285-59:
(6*4)+(5*2)+(4*8)+(3*5)+(2*5)+(1*9)=100
100 % 10 = 0
So 4285-59-0 is a valid CAS Registry Number.

A catalytic conversion method for preparing pyruvate ester of lactic acid (by machine translation)

-

Paragraph 0022, (2016/10/10)

A method for preparing pyruvate through catalytic conversion of lactic acid is provided; according to the method, with oxygen or air as an oxidant, alcohol as a solvent, and molybdovanadophosphoric heteropoly acid and/or tungstovanadophosphoric heteropoly acid as a catalyst, and by coupling of a catalytic oxidation reaction and an esterification reaction, lactic acid is converted into pyruvate by one step. The method directly adopts oxygen or air as the oxidant and is green and safe; the used raw material lactic acid is obtained directly from conversion of biomass resources, moreover, the reaction conditions are mild, and the method has important application prospects.

Photocatalytic reaction of arylamines/alcohols on TiO2 nano-particles

Hosseinnia, Azarmidokht,Pazouki, Mohammad,Karimian, Ketauon

experimental part, p. 373 - 381 (2011/10/19)

In this article, the photocatalytic reaction of aniline and 4-amino N,N-dimethyl aniline with methanol, ethanol and isopropanol on anatase TiO 2 nano-particles under UV (365-nm wavelength) irradiation was examined. The concentration of unreacted arylamines and products was measured by gas chromatography picks integration, and then the products were identified by mass spectroscopy analysis. By making a comparison within the rates of photocatalysis of each arylamine in different alcohols under various irradiation times, it was revealed that, in all cases, the sequence of photocatalysis rate was methanol > ethanol > isopropanol. In reactions where the concentrations of arylamine were lower than 10 mmol/l, imines were the main products and the alkylation of amines was not observed. In the higher concentration of arylamines, oxidation and dimerization was occurred. Springer Science+Business Media B.V. 2010.
