2998-18-7 Usage

General Description

SEC-BUTYL METHACRYLATE is a chemical compound that is commonly used as a monomer in the production of various polymeric materials, such as plastic coatings, adhesives, and protective films. It is a clear, colorless liquid with a characteristic mild odor, and it is highly flammable. SEC-BUTYL METHACRYLATE is known for its fast curing and excellent adhesion properties, making it a popular choice in the automotive, construction, and electronics industries. It is also used in the formulation of specialty chemicals and as a reactive diluent in various coating applications. However, prolonged exposure to SEC-BUTYL METHACRYLATE may cause irritation to the skin, eyes, and respiratory system, and it should be handled with care in a well-ventilated environment.

Check Digit Verification of cas no

The CAS Registry Mumber 2998-18-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,9 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2998-18:
(6*2)+(5*9)+(4*9)+(3*8)+(2*1)+(1*8)=127
127 % 10 = 7
So 2998-18-7 is a valid CAS Registry Number.

Increased activity of enzymatic transacylation of acrylates through rational design of lipases

Syren, Per-Olof,Lindgren, Ebba,Hoeffken, Hans Wolfgang,Branneby, Cecilia,Maurer, Steffen,Hauer, Bernhard,Hult, Karl

experimental part, p. 3 - 10 (2011/02/22)

A rational design approach was used to create the mutant Candida antarctica lipase B (CALB, also known as Pseudozyma antarctica lipase B) V190A having a kcat three times higher compared to that of the wild type (wt) enzyme for the transacylation of the industrially important compound methyl methacrylate. The enzymatic contribution to the transacylation of various acrylates and corresponding saturated esters was evaluated by comparing the reaction catalysed by CALB wt with the acid (H2SO4) catalysed reaction. The performances of CALB wt and mutants were compared to two other hydrolases, Humicola insolens cutinase and Rhizomucor mihei lipase. The low reaction rates of enzyme catalysed transacylation of acrylates were found to be caused mainly by electronic effects due to the double bond present in this class of molecules. The reduction in rate of enzyme catalysed transacylation of acrylates compared to that of the saturated ester methyl propionate was however less than what could be predicted from the energetic cost of breaking the π-system of acrylates solely. The nature and concentration of the acyl acceptor was found to have a profound effect on the reaction rate.
