Flammability and Explosibility

Nonflammable

Check Digit Verification of cas no

The CAS Registry Mumber 2416-94-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,1 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2416-94:
(6*2)+(5*4)+(4*1)+(3*6)+(2*9)+(1*4)=76
76 % 10 = 6
So 2416-94-6 is a valid CAS Registry Number.

Catalytic activity of a mordenite catalyst in alkylation of xylenols with methanol

Agaev,Madatzade

, p. 683 - 684 (2005)

The catalytic activity of a palladium-containing mordenite catalyst in alkylation of 2,6-, 2,4-, 2,5-, 2,3-, 3,4-, and 3,5-xylenols with methanol was studied. The main and by-products of catalysis and the activity of the catalyst in synthesis of individual trimethylphenols were determined.

Vapor phase methylation of m-Cresol over Ce-impregnated Cd1-xCrxFe2O4 (x = 0, 0.25, 0.50, 0.75 and 1.0) ferrospinels

Kadian, Malvika,Gupta

, p. 905 - 907 (2017)

Cd-Cr ferrospinels prepared by co-precipitation method were impregnated with cerium as promoter. Ce-impregnated ferrospinels were tested for the vapor phase alkylation of m-cresol with methanol. It has been observed that with increase in value of 'x' in C

Deoxyalkylation of guaiacol using haggite structured V4O6(OH)4

Yan, Fei,Wen, Zhe,Wu, Kai,Cui, Kai,Mai, Fuhang,Ma, Zewei,Sang, Yushuai,Bai, Yunfei,Chen, Hong,Li, Yongdan

, p. 1922 - 1932 (2019/04/29)

When V2O5 is used for the deoxygenation of guaiacol in methanol, it is reduced in situ to haggite structured V4O6(OH)4. Guaiacol prevents further reduction of the haggite phase in methanol and haggite catalyzes the partial deoxygenation of guaiacol. Haggite is a metastable redox catalyst for the deoxygenation of guaiacol, which follows the reverse Mars-van Krevelen mechanism. In addition, haggite is also a Lewis acid catalyst and catalyzes the alkylation of guaiacol with methanol as the alkylation reagent. The main products of the guaiacol deoxyalkylation are 2,6-dimethylphenol, 2-methoxy-6-methylphenol, 2,4,6-trimethylphenol, 2,3,6-trimethylphenol, 2,3,5,6-tetramethylphenol and 6-methyl-2-tert-butylphenol. Oligomerization takes place during the reaction but it is reversible. When the reaction is performed at 300 °C for 6 h, the 83.5% total selectivity for alkylphenols is achieved with a 99.0% conversion.

Catalyst for synthesis of 2, 3, 6-trimethylphenol and preparation method thereof

-

Paragraph 0017; 0018; 0019; 0020; 0023, (2018/09/11)

The invention discloses a catalyst for synthesis of 2, 3, 6-trimethylphenol and a preparation method thereof, and relates to a catalyst and a preparation method thereof. The catalyst for the synthesisof the 2,3,6-trimethylphenol from m-cresol comprises Fe2O3, SiO2 and CuO. In the preparation, Fe(NO3)3.9H2O is dissolved in deionized water, then Na2SiO3.9H2O and Cu(NO3)2.3H2O are added in sequence,and then dissolved to obtain a mixture A; ammonia water is added to the mixture A, stirred, aged, cooled to room temperature, and filtered by suction, and a filter cake is dried and calcined to obtain the catalyst for the synthesis of the 2,3,6-trimethylphenol from the m-cresol. The catalyst is free of precious metals and toxic heavy metals, low in cost, environmentally friendly, simple in preparation method, good in catalytic activity and high in selectivity, m-cresol conversion rate can reach 100%, and selectivity of the 2,3,6-trimethylphenol can reach 97.9%.
