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 ...
photochemical reaction - a chemical reaction produced by the action of light reducing, reduction - any process in which electrons are added to an atom or ion (as by removing oxygen or adding hydrogen); always occurs accompanied by oxidation of the reducing agent saponification - a chemical reacti...
Furthermore, the interactions between aglycone components (i.e., sapogenin) and sterols of the cell membranes can result in a saponification process that may lead to cell lysis (Bahrami et al. 2016). Table 7.3 Triterpene glycosides of different orders of holothurians and their bioactivity Full ...
Ester is the name given to types of organic compounds that form from the replacement of the -OH group from an acid with the hydrocarbon chain, R, from an alcohol. When you combine the acid and an alcohol, they go through the process of making an ester, known as esterification. Although...
Although these two substances aren’t the same, theyarelinked: many living things convert ammonia (which is very toxic) to urea (which is much less so) aspart of normal metabolism. And it also goes the other way, in a process calledurea hydrolysis. This reaction happens in urine once it’...
Frozen yeast pellets (~50 mg, fresh weight) were mixed with 0.5 ml saponification reagent (20% KOH in 50% ethanol, vol/vol) and incubated at 65 °C for 2 h before extraction with an equal volume of hexane (0.5 ml). The hexane extraction was repeated (2×) to maximize...
Solid-phase extraction-thin-layer chromatography-gas chromatography method for the detection of hazelnut oil in olive oils by determination of esterified s... Similar results were achieved with both methods; however, the SPE–cold saponification–TLC–capillary GC was faster, required less solvent and...
Conductance change in ethyl acetate saponification reaction: Ethyl acetate reacts with sodium hydroxide to produce sodium acetate and ethanol, and the sodium acetate produced in the process results in an increase in the conductivity of the solution. The change in conductivity reflects the reaction prog...
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. [...
