Optimization of Cellulose Acetate with Acetylation from Empty Fruit Bunch (EFB) using Respon Surface Methodology (RSM) [PDF]

E3S Web of Conferences
Empty fruit bunches (EFB) are a kind of biomass waste from the palm oil industry with a cellulose content of 45.95%. Cellulose can be modified into cellulose acetate through an acetylation process, resulting in a product that has the potential to be ...

Separation of dolichol from dehydrodolichol by a simple two-plate thin-layer chromatography.

Journal of Lipid Research, 1992
A novel thin-layer chromatographic procedure was devised to separate dolichol and dehydrodolichol from each other with the concomitant separation of each family with respect to the carbon chain length.

Enzymatic conversion reactions of 5-hydroxymethylfurfural (HMF) to bio-based 2,5-diformylfuran (DFF) and 2,5-furandicarboxylic acid (FDCA) with air: mechanisms, pathways and synthesis selectivity

Biotechnology for Biofuels, 2020
Background 2,5-Furandicarboxylic acid (FDCA) is one of the top biomass-derived value-added chemicals. It can be produced from fructose and other C6 sugars via formation of 5-hydroxymethilfurfural (HMF) intermediate.

Chemical Reaction Spectrum [PDF]

, 2018
We proposed a new method of chemical reaction spectrum (CRS) in terms of chemical characterization, and established a method to fulfill it by combining with 3D chemical printing technology and 2D sampling.

Liquid-liquid extraction with and without a chemical reaction [PDF]

, 2011
The extraction of mercaptans with alkaline solution is accompanied by a second- order instantaneous reaction. As explained in Section 2.2, in this case, the mass transfer coefficients can be calculated as for the physical extraction, since the mass ...

Peripheral chemical reactions

Chemical Physics Letters, 1993
Abstract Forward scattering of the products of direct exoergic atom transfer reactions is proposed as an indication for a peripheral attraction: a reaction in which an atom at the periphery of the reactants is abstracted. Model computations for the O( 1 D) + N 2 O reaction are used to illustrate the proposed mechanism. The opacity function has a peak
