摘要:
This invention relates to the design of a process by intermittent dielectric heating combined with a recycling system.This process consists in subjecting reagents to electromagnetic waves selected in the frequencies ranging between 300 GHz and 3 MHz intermittently using a recycling system.This process enables the treatment of oils that are hardly absorbent as well as great investment savings.This process enables operation on different scales, whether in laboratories, on a semi-industrial or industrial scale, without forfeiting the advantages of continuous dielectric heating.
摘要:
This invention proposes a lanolin substitute, capable of absorbing up to at least twice its weight of water or aqueous solution or aqueous suspension. It forms true emulsions, stable over time with a capacity for water absorption superior to that of lanolin.It also possesses the known emollient, moisturizing and occlusive properties of lanolin.This substitute is usable in all the present and future areas of application of lanolin: in the cosmetics industry, dermatology, and in industrial applications (polishes, lubricants . . . ).It is obtained by hemi-synthesis from a mixture of unsaturated fatty acids, esters of unsaturated fatty acids, unsaturated hydrocarbons or unsaturated derivatives of the latter and compounds comprising or generating hydroxyl functions, such as glycerol, preferably without a catalyst and in an atmosphere devoid of oxygen.Classical thermal treatment or preferably treatment by dielectric heating.

摘要:
This invention relates to a process of polymerization of unsaturated fatty acids, esters of unsaturated fatty acids, unsaturated hydrocarbons or esters of unsaturated hydrocarbons, or unsaturated derivatives of these products by dielectric heating, as well as to the polymers obtained and uses of these polymers. The polymerization process is characterized by the fact that the reagent or reagent mixture is subjected to dielectric hearting to effect polymerization.

摘要:
A dielectric heating system with which the power density applied to the product being treated can be at least doubled without risk of electric arcs. This invention is particularly suitable for treatment of compounds that absorb electromagnetic waves weakly (low dielectric constants). In particular, fatty substances such as oils, butters, waxes and fats can be treated (refining, hydrolysis, transesterification, interesterification, etc.), derivatives thereof (esterification, polymerization, alcoholysis, ethoxylation, hydrogenation, etc.) under static or dynamic conditions, as can hydrocarbons and aromatic compounds. This system can also be used advantageously for polar or polarized compounds, because the power absorbed is increased very significantly, with large production gains. In particular, fatty or non-fatty alcohols (oleic alcohol, glycol, glycerol, mannitol, sorbitol, polyglycerols, vitamins, etc.), carboxylic acids, amines and similar compounds can be treated under static or dynamic conditions.
