41444-57-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41444-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,4 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 41444-57:
99 % 10 = 9
So 41444-57-9 is a valid CAS Registry Number.

Preparation of Long-Chain Alkyl Glucoside Surfactants by One-Step Direct Fischer Glucosidation, and by Transacetalation of Butyl Glucosides, on Beta Zeolite Catalysts


, p. 218 - 224 (1998)

Long-chain alkyl glucoside surfactants have been obtained with good conversions and selectivities by the transacetalation of butyl glucosides with different fatty alcohols as well as by one-step direct glycosidation, using H-Beta zeolites as catalyst. The influence of the different process variables such as temperature, molar ratio of reactants, and fatty alcohol chain length has been investigated. Moreover, the study of the transacetalation process in the presence of H-Beta zeolites with different hydrophobic-hydrophilic properties has shown the strong influence of this zeolite property on catalyst deactivation. The rate of decay is lower for the more hydrophobic Beta Samples.

Selective Primary Alcohol Oxidation of Lignin Streams from Butanol-Pretreated Agricultural Waste Biomass

Panovic, Isabella,Lancefield, Christopher S.,Phillips, Darren,Gronnow, Mark J.,Westwood, Nicholas J.

, p. 542 - 548 (2019/01/14)

Chemically modified lignins are important for the generation of biomass-derived materials and as precursors to renewable aromatic monomers. A butanol-based organosolv pretreatment has been used to convert an abundant agricultural waste product, rice husks, into a cellulose pulp and three additional product streams. One of these streams, a butanol-modified lignin, was oxidized at the γ position to give a carboxylic acid functionalized material. Subsequent coupling of the acid with aniline aided lignin characterization and served as an example of the flexibility of this approach for grafting side chains onto a lignin core structure. The pretreatment was scaled up for use on a multi-kilogram scale, a development that enabled the isolation of an anomeric mixture of butoxylated xylose in high purity. The robust and scalable butanosolv pretreatment has been developed further and demonstrates considerable potential for the processing of rice husks.

Influence of acyl groups on glucopyranoside reactivity in Lewis acid promoted anomerisation

Farrell, Mark P.,Doyle, Lisa M.,Murphy, Paul V.

supporting information, p. 2726 - 2731 (2018/06/20)

Lewis acid promoted anomerisation has potential in O- or S-glycoside synthesis. Herein, the anomerisation kinetics of thirty-one β-D-glucopyranosides was determined to determine how particular acyl protecting groups and their location influence reactivity towards a Lewis acid promoted reaction. The replacement of acetyl groups with benzoyl groups led to reduced reactivity when located at O-3, O-4 and O-6. However a reactivity increase was observed when the acetyl group was replaced by a benzoyl group at O-2. The 2,3,4,6-tetra-O-(4-methoxy)benzoate had an ~2-fold increase in rate when compared to the tetrabenzoate.
