The preparation technology of biodiesel and chemical products from natural oils was summarized,the synthesis method and application areas of three kinds of chemical products of C_(21) dibasic acid,C_(22) tribasic acid and C_(36) dimer from natural oils were introduced,too.
The result shows that the molecular structure of low caloric fat is as same as that of natural oils,the sense quality has no difference with common oils,the calorific power decreases by 30% than that of peanut oil.
The sulfited Fatliquor FP-I was prepared when molar ratio of natural oils and fats, polyethyleneglycol, maleic anhydride and sodium bisulfated(NaHSO 3) was 1:3.5:3:3 and temperature of alcoholysis, esterification and sulfiting reaction was 150 ℃, 90 ℃ and 75 ℃ respertively.
A HX -2 type deinking agent containing the adduct of epoxide and a mixture of natural fat and polyhydric alcohol was developed with reference to the Japanese patent JP60 - 239585. Both the whiteness of the deinked paper and the number of the residue ink can meet the requirement by using this deinking agent.
The hydrogenation of natural fats and oils has been widely used in food industry, for example, the stearin obtained from coconut oil can substitute cocoa grease or is used as raw material of margarine.
High oil absorption resin, being different from ordinary oil absorbent materials, is a new self-swelling oil absorption material. It could absorb a great variety of oils from mineral oil to natural fats and oils.
This paper discusses the kinetic mechanism of exter - exchange reaction and the influence factors on ester-exchange reaction of oil and fat as well as its applications in developping Leather fatliquor agent of natural oil and fat.
Biodiesel produced by transesterification of natural oil with alcohols is an environmental friendly alternative fuel. With a traditional homogeneous acid/base catalyst, separating transesterification product with used catalyst is difficulty. Discharge of waste catalyst induces environmental problems.
A procedure is developed for the determination of maleic anhydride in maleinized adducts based on natural oils by the reaction yielding molecular complexes of 2-methylimidazole and maleic anhydride in dimethyl sulfoxide.
The application of this system is demonstrated by the analysis of C6-C8 aromatic hydrocarbons and lowboiling hydrocarbons present in natural oils, and of highboiling components present in low concentrations in a low-boiling solvent.
The Flory-Huggins interaction parameter,κ1,2,∞, was determined for a number of fractions separated from vacuum distillation residues of natural oils.
The Flory-Huggins interaction parameter, κ1,2∞, was determined for a number of fractions separated from vacuum distillation residues of natural oils.
The effect of inoculum, pH, carbon and nitrogen source, natural oils, fatty acids, antioxidant, and precursors on β-carotene production by Blakeslea trispora in shake-flask culture was investigated.
To account quantitatively for many reported "natural" fat tail distributions in Nature and Economy, we propose the stretched exponential family as a complement to the often used power law distributions.
Corynebacterium acnes was cultered in a medium emulgated with triglycerides as well as in a medium from which the total natural fat content was previously extracted.
Hydrogenated fats compare favorably with a natural fat of comparable firmness in serving as a source of essential fatty acids.
Despite this, the simplicity of the technique and its rapid and relatively reliable applicability to the widest variety of problems of natural fat characterization recommends it as one of the methods in any fat test or control laboratory.
Symposium on analysis of natural fat triglycerides
An association of four bacterial strains with high oil-oxidizing and bioemulsifying activities, psychrophilicity, resistance to chemical pollutants, and lack of pathogenicity was selected from a collection of natural oil-oxidizing microorganisms.
56 isolated from natural oil-containing soil samples taken near the city of Oktyabr'skii, Republic of Bashkortostan, displayed a pronounced capability of biotransforming oil and its light and heavy fractions.
CCI in natural oil-saturated core samples has been experimentally investigated.
Therefore, the structures of model (micellar) and natural (oil) disperse systems are compared for the first time, and the correlation between their behavior upon heating is revealed.
In vivo, oleosin fusions are produced and directly localized to natural oil bodies in transgenic plant seeds.
