Compositions, methods, and resins using alkyl aldehydes and phenols are provided herein. In one embodiment, a composition comprising an alkylphenol resin can be prepared by condensing at least one phenolic monomer selected from the group consisting of phenol, cresol, resorcinol, xylenol, ethyl phenol, alkylresorcinols, and combinations thereof; and at least one alkyl aldehyde having from 5 to 12 carbon atom alkyl groups. The alkylphenol resins of the application are free of octylphenol or nonylphenol monomers. In one embodiment, the alkylphenol resins may be prepared using formaldehyde, and alternatively, in another embodiment, the alkylphenol resins may be prepared without the use of formaldehyde. The process to make these new alternative alkylphenol resins is a cost effective process and easy to scale-up.

A modified alkylresorcinol resin is prepared by reacting one or more alkylresorcinols with one or more aldehydes and optionally an olefinically unsaturated compound, The reaction may be carried out in the presence of a catalyst. The resulted modified alkylresorcinol resin can be used as a methylene acceptor that reacts with methylene donors in vulcanizable rubber compositions.

The present invention discloses an agent for external application to the skin which is hardly reduced in viscosity even when stored for a long period under extreme high temperature storage conditions and is therefore stable. The agent is of an emulsion-type, and comprises 1) an alginic acid polyhydric alcohol ester having an esterification degree ranging from 75 to 95% (e.g., alginic acid propylene glycol ester) and / or a salt thereof, 2) a polyvalent metal ion (e.g., a calcium ion); and 3) a 4-alkylresolcinol (e.g., 4-n-butylresolcinol) and / or a salt thereof.

The invention discloses a wheat aleurone layer content (namely wheat aleurone layer powder) cooked product and application thereof. The wheat aleurone layer content cooked product is a powder product which has a moisture content of less than 8% and is obtained by cooking a wheat aleurone layer content, the average granularity of the wheat aleurone layer content cooked product is less than 75 microns, and every 100g of the wheat aleurone layer content cooked product contains not lower than 35g of dietary fiber, not lower than 130mg of alkylresorcinol, not lower than 800mg of phosphorus and not lower than 18g of pentosan. The wheat aleurone layer content cooked product is formed through the steps of screening of the wheat aleurone layer content, full-automatic quantitative feeding, stir-frying, automatic discharging, quick cooling, metal detection, sterilization packing and the like. The wheat aleurone layer content cooked product can be used as a fluid beverage additive, puffed food, a health-care dietary fiber product, a functional health-care product or a nutritional health-care product rich in wheat physiological active ingredient with high nutritional value.

The present invention relates to an alkyl resorcinol compound and uses thereof, and specifically provides uses of an alkyl resorcinol compound represented by the following general formula (I), a pharmaceutically acceptable salt, a solvate, a stereoisomer and a tautomer thereof in preparation of pharmaceutical compositions or preparations for prevention and / or treatment of eye diseases. According to the present invention, the alkyl resorcinol compound has excellent treatment effects on eye diseases such as age-related macular degeneration, diabetic retinopathy, xerophthalmia and the like. The formula (I) is defined in the specification.

The invention belongs to the technical field of chemical synthesis and in particular relates to a preparation method of a cardanol modified alkylresorcinol-formaldehyde resin. The preparation method comprises the following steps: (1) putting resorcinol, cardanol and p-toluenesulfophenol into a reactor to be mixed uniformly and heating the mixture; (2) dropwise adding styrene and maintaining for 1.5 hours after dropping; (3) cooling the mixture, beginning dropwise adding a formaldehyde solution and reacting at the reduced temperature for 2 hours after dropping; and (4) adding a pH regulator to regulate the pH to 7 and then carrying out heating, distilling and dehydrating to obtain a red brown transparent resin, thus obtaining the cardanol modified alkylresorcinol-formaldehyde resin. The modified alkylresorcinol-formaldehyde resin has better intermiscibility with rubbers and better flexibility, and meanwhile, the product cost is greatly reduced.

The invention belongs to the technical field of weight-loss products, and particularly relates to application of alkyl resorcinol to preparation of a product for preventing or treating obesity relateddiseases. The application of the alkyl resorcinol to preparation of the product for preventing and / or treating the obesity related diseases and improving energy metabolism and heat production of a body is characterized in that the product contains the active ingredient alkyl resorcinol, the alkyl resorcinol is prepared from the following monomers in percentage by weight: 1-10% of heptadecyl resorcinol, 20-25% of nonadecyl resorcinol, 50-55% of heneicosyl resorcinol, 5-10% of tricosyl resorcinol and 5-12% of pentacosyl resorcinol. According to the application, the appropriate ratio of each constituent monomer corresponding to the prevention or treatment of the obesity by improving the energy metabolism of the body or improving the heat production of the body through the alkyl resorcinol isdefined.

The invention relates to the technical field of organic synthesis, in particular to a method for synthesizing 4-alkylresorcinol through a solvent-free system. The method comprises the following stepsthat (1) resorcinol, zinc chloride and alkyl acid are evenly mixed, heated and stirred for a reaction, after cooling, water is added to precipitate a solid, filtering, drying and recrystallization areconducted, and thus 4-acylresorcinol is obtained; (2) the 4-acylresorcinol is dissolved into trifluoroacetic acid, triethyl silicane is added dropwise, heating and stirring are conducted for a reaction, cooling and standing are conducted for layering, an organic layer is extracted and dried, filtration and concentration are conducted to obtain a crude product, recrystallization is conducted, andthe 4-alkylresorcinol is obtained. According to the method, a triethyl silicane / trifluoroacetic acid system is applied to synthesis of the 4-alkylresorcinol for the first time, the reaction conditionis gentler and easier to control, and a post-treatment method is simple; and the system does not contain a solvent, water materials generated during industrial amplification are also greatly reduced,and thus the whole process is more environment friendly.
