Glycerine carbonate

Glycerol can be converted into glycerine carbonate via an oxidative carbonylation and, subsequently, into glycidol (Scheme 11.18) [136]. 

The small addition of sulphur is also converted into gas, sulphurous acid, whereas the barium nitrate and manganese at a high temperature give off a large quantity of free osygen which effects the entire combustion of nitro-glycerine, carbon, bran, sawdust and sulphur, and causes the highest possible temperature.

Evaporators have performed successfully in a number of industrial applications. Typical materials that are processed in evaporators include Caustic Soda, Caustic Potash, Sodium Carbonate, Sodium Dichromate, Sodium Nitrate, Ammonium Nitrate, Phosphoric Acid Superacid, Potash, Urea, Glue, Glycerine,... 

Decreases with increasing wettability of liquid on plate surface. Kerosene, hexane, carbon tetrachloride, butyl alcohol, glycerine-water mixtures all wet the test plates better than pure water. The critical tray stability data of Hunt et al., [33] is given in Table 8-21 for air-water, and hence the velocities for other systems that wet the tray better than water should be somewhat lower than those tabulated. The data of Zenz [78] are somewhat higher than these tabulated values by 10-60%. 

Elsewhere, in a series of Japanese patents, mixtures of resorcinol + sodium nitrate, glycerine + sodium nitrate, lithium hydroxide + tungstate, etc., have been claimed to be effective. An example of the use of inhibited cooling mixtures of low toxicity is provided by a patent which describes a mixture of silicate-I- polyphosphate -I- a saccharide, e.g. sucrose or fructose, as the inhibitor formulation in a propylene glycol -I- potassium-hydrogen-carbonate mixture used in aluminium cooler boxes for ice-cream.

Hogan (H12) obtained Rc values of 0.01-10 C/kg. With dibutyl phthalate, however, he reports a mode of atomization in which no liquid jets could be seen with a microscope and for which Rc values of 105 C/kg were measured, corresponding to singly ionized dimer molecules. No particles could be formed with silicone pump oil, whereas charges of 200-400 C/kg were obtained with suspensions of either Cab-0-Sil4a or carbon in glycerine. 

Seed oil triglycerides consist of three fatty acids esterified to glycerin. Although most plants produce at least some Cie fatty acids, the majority of the triglycerides are comprised of Cig fatty acids. The balance of the fatty acids is quite specific to the plant from which the oil is derived, but the most prominent fatty acids among all plant species consist of a series of 18-carbon fatty acids containing zero, one, two, or three sites of unsaturation. These fatty acids are stearic, oleic, linoleic, and linolenic acids, respectively. These are the main fatty acids found in most seed oils and are illustrated in Fig. 5. 

The composition of seed oil triglycerides is well understood. Triglycerides are fatty acid esters of glycerin, and the composition depends on the source of the oil (Figure 2). The nomenclature used is standard in the fats and oils industry, with the number of carbons in the fatty acid indicated first, followed by the number of sites of unsaturation in parentheses. 

Industrial processes tend to favor base catalysis, since they have lower activation energies allowing the reactions to be carried out near or just above room temperature (5). Further, the carbonate or caustic bases are relatively inexpensive and easily separated with the glycerin product.
