The present invention relates to a process for chemical recycling of PET waste that comprises, among other stages, a saponification reaction stage, wherein PET waste particles are reacted with stoichiometric or excessive amounts of a strong base metal in an alcoholic reaction media, the reaction ...
Chemical process safety is part of a comprehensive safety assessment for scale-up and manufacturing and must therefore be regarded as part of company culture and policy. The guideline under which Chemical Process Safety falls is also known as "HSE" or "SHE", and is included in the directives...
bottom). Expression of OSC genes during the planktotrophic stage of larval development, in which larvae actively feed on algae and plankton in the top water column, could be associated with the production of
Chemical cleaning is based on chemical reactions – hydrolysis, saponification, solubilisation, dispersion, chelation, and/or peptisation – to break down bonds and cohesion forces between the membrane surface and the foulants [32]. Commonly used chemical cleaners for membrane systems are given in Ta...
These types of pectin do not usually exist alone and are often composed of RG-I, homogalacturonan (HG), and AG structures. Sun et al. [18] isolated a series of RG-I and RG-II domains from ginseng pectin by alkali saponification and endo-polygalacturonase hydrolysis. Gao et al. [...
Methanol (methyl alcohol) was originally produced by heating wood chips in the absence of air. Some of the carbohydrates in the wood are broken down to form methanol, and the methanol vapour is then condensed. This process led to the name w
Removal of 4-nonylphenol using magnetite modified with silica based molecularly imprinted polymers Raden Tina Rosmalina, Nurrahmi Handayani, Diana Rahayuning Wulan, Ee Ling Yong, Shamila Azman Pages 361-373 select article Underlying laws governing the saponification and crystallization separation of free...
These intermediates are produced by saponification or transesterification of oils and fats, respectively. Fatty acid esters are used as biodiesel, a renewable transportation fuel with properties comparable to conventional petrodiesel. Fatty acid esters and free fatty acids are converted to fatty alcohols ...
process generated due to addition of nanoparticles is attributable to their scalable and quantum effects. The application of this functional materials requires a base fluid such as gas, oil, water, or any other suitable liquid substance, hence, they are termed nanofluid. The application of ...
discloses a process for the saponification of ethylene-saturated carboxylic acid vinyl ester copolymers, wherein the saponification reaction is carried out in a solution of the reactant in an organic solvent such as xylene having a concentration of up to 60% by weight. So, in this process, it...
