Triglyceride 3 NaOH / H 2 O Δ 3 × soap 3 × glycerol Triglycerides can be saponified with sodium hydroxide to give glycerol and fatty sodium salt or soap. Typical plant sources include soybeans or palm. Animal-derived tallow is another source. Approximately 950,000 tons per year are produced in the United States and Europe; 350,000 tons of glycerol were produced per year in the U.S. alone ...
In chocolate, compound chocolate and similar coatings, PGPR is mainly used with another substance like lecithin [2] to reduce viscosity. It is used at low levels (below 0.5%), [ 3 ] [ 4 ] and works by decreasing the friction between the solid particles (e.g. cacao , sugar , milk ) in molten chocolate, reducing the yield stress so that it flows ...
Glycerine acetate is a mixture of esters produced from the esterification of glycerol (1) with acetic acid. This reaction produces five congeners: the two monoacetylglycerols / MAG / monoacetin (2 and 3) the two diacetylglycerols / DAG / diacetin / glyceryl diacetate (4 and 5) the one triacetalglycerol / TAG / triacetin (6)
1,3-Propanediol is mainly produced by the hydration of acrolein. An alternative route involves the hydroformylation of ethylene oxide to form 3-hydroxypropionaldehyde. The aldehyde is subsequently hydrogenated to give 1,3-propanediol. Biotechnological routes are also known. [2] Two other routes involve bioprocessing by certain micro-organisms:
Propanethiol is an organic compound with the molecular formula C 3 H 8 S. It belongs to the group of thiols.It is a colorless liquid with a strong, offensive odor. It is moderately toxic and is less dense than water and slightly soluble in water.
sn-Glycerol 3-phosphate [a] [b] is the organic ion with the formula HOCH 2 CH(OH)CH 2 OPO 3 2-. It is one of two stereoisomers of the ester of dibasic phosphoric acid (HOPO 3 2- ) and glycerol . It is a component of bacterial and eukaryotic glycerophospholipids . [ 2 ]
In January, the state gave YSI a $7.3 million, five-year contract to run the new Broward Youth Treatment Center, a 28-bed program less than a mile away from Thompson. And this summer, YSI won contracts to take over two more state facilities, one in the Tampa area and another in Jacksonville. Read the first part of this series »
In aqueous solution 3-hydroxypropionaldehyde exists in equilibrium with its hydrate (1,1,3-propanetriol), in which the aldehyde group converts to a geminal diol: HOCH 2 CH 2 CHO + H 2 O → HOCH 2 CH 2 CH(OH) 2. The hydrate is also in equilibrium with its dimer (2-(2-hydroxyethyl)-4-hydroxy-1,3-dioxane), which dominates at high concentrations ...
