3228-03-3 Usage

Uses

5-Isopropyl-3-methylphenol is a derivative of Carvacrol (C184600); a major phenolic component of oregano oil and a novel inhibitor of the Mycobacterium tuberculosis (MTB) chorismate mutase (CM) enzyme.

Check Digit Verification of cas no

The CAS Registry Mumber 3228-03-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,2 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3228-03:
(6*3)+(5*2)+(4*2)+(3*8)+(2*0)+(1*3)=63
63 % 10 = 3
So 3228-03-3 is a valid CAS Registry Number.

Method of preparing 3-isopropyl-5-cresol and carvacrol with 3-carene

-

Paragraph 0064; 0065; 0066; 0067; 0068; 0069; 0070-0074, (2019/02/04)

The invention discloses a method of preparing 3-isopropyl-5-cresol and carvacrol with 3-carene. The method comprises the following steps that 3-carene is reacted with oxygen at a room temperature to produce a product I under the catalysis of CrO3-Al2O3, wherein the product I is prepared from the main components including 5-carone, 2-carone and 4-carone with the selectivity ratio being about 10.8 to 3.5 to 1.0; the product I is distilled to recover 3-carene, wherein the recovery rate is larger than 80 percent, and the recovery purity is larger than 94 percent; the residual components are converted to a product II at 230 DEG C under catalysis of a 13X type molecular sieve, and reduced pressure distillation is performed on the product II to obtain a mixed phenol product with the purity largerthan 96 percent, wherein the product II is prepared from the main components including 3-isopropyl-5-cresol and carvacrol, the raw material conversion rate is 100 percent, the total selectivity of phenolic products can reach 98 percent, and the selectivity ratio of the two phenolic products is about 2.2 to 1.0; and column chromatography isolation is performed on the product II to obtain 3-isopropyl-5-cresol and carvacrol with the purities larger than 97 percent respectively.

Improving carbon retention in biomass conversion by alkylation of phenolics with small oxygenates

Nie, Lei,Resasco, Daniel E.

, p. 14 - 21 (2013/02/25)

Alkylation of phenolics with alcohols is an efficient way to retain carbon from small oxygenates in the liquid products of pyrolysis bio-oil. In this contribution, we have investigated the alkylation of m-cresol with several alkylating agents over H-Beta zeolite. The alkylation activity follows the sequence 2-propanol > propylene > 1-propanol. In all cases, propylene is the actual alkylation agent since the alcohols dehydrate at a faster rate than the rate of alkylation. A two-stage process is proposed to convert fractions of bio-oil rich in small aldehydes and ketones together with phenolics. In the first stage, aldehydes and ketones are selectively hydrogenated to alcohols. In the second stage, the resulting alcohols alkylate the phenolic compounds and get incorporated into the upgraded liquid. To illustrate this concept, two consecutive catalyst beds have been used. The first bed contains a metal catalyst for the selective hydrogenation. Among several catalysts investigated, Cu/SiO2 and Pt-Fe/SiO2 were found to exhibit good selectivity to hydrogenate the aldehyde and ketone, respectively, while preserving the aromatic ring of the phenolic compound. The second bed contains an H-Beta zeolite for the alkylation stage.

2DCOR-GC: An application of the generalized two-dimensional correlation analysis as a route to optimization of continuous flow supercritical fluid reactions

Hyde, Jason R.,Bourne, Richard A.,Noda, Isao,Stephenson, Phil,Poliakoff, Martyn

, p. 6197 - 6206 (2007/10/03)

A new approach for optimization and monitoring of continuous reactions has been developed using 2D correlation methods for the analysis of GC data (2DCOR-GC). 2DCOR-GC maps are obtained following perturbation of the system that allow the effect of changing reaction parameters such as time, temperature, pressure, or concentration to be both monitored and sequenced with regard to changes in the raw GC data. In this paper, we describe the application of the 2DCOR-GC technique to monitoring the reverse water-gas shift reaction in scCO2. 2DCOR-GC is combined with FT-IR data to validate the methodology. We also report the application of 2DCOR-GC to probe the mechanism of the alkylation of m-cresol with isopropyl alcohol in scCO2 using Nafion SAC-13 as the catalyst. These results identify coeluting peaks that could easily be missed without exhaustive method development.
