Prior art

Derivatives acetals polyhydric alcohols can be used for various purposes, including, for example, used as nucleation agents for polymer resins, as well as gelling agents and thickening agents for organic liquids. It is known that these purposes can be used connection type dibenzylideneacetone (DBS).

The use of nucleation agents to reduce the turbidity of products made from crystalline polyolefin resins, known in the art. Typical acetals of sorbitol and xylitol, which were used as brightening agents are described in several patents, including, for example, U.S. patent No. 4016118, Hamada et al.(dibenzylideneacetone); U.S. patent No. 4314039, Kawai et al. (di(alkylbenzenes)sorbite)); U.S. patent No. 4371645, Mahaffey, Jr. (diacetyl sorbitol having at least one atom of chlorine or bromine as a substituent); U.S. patent No. 4954291, Kobayashi et al. (distribution of diacetals sorbitol and xylitol made from a mixture of dimethyl - or trimethylsilanol benzaldehyde and unsubstituted benzaldehyde). In other work, and there is but in U.S. patent No. 5049605, Reckers et al., described bis(3,4-dialkylanilines)sorbite containing substituents, forming a carbocyclic ring.

The substitution of various groups in the position(s) benzyl ring DBS connections can significantly affect the suitability of these compounds as nucleation agents or bleaching agents. A significant number of previous works focused on the modification of substitution of the substituent(s) benzylidene rings. However, at present, attempts are being made to obtain other compounds that also would reduce the turbidity (and thus would increase the transparency of the polymer when used as plastic additives in polymer compositions.

The result of chemical transformations is often unpredictable. Change any part or substituted groups in the compounds of a specific type can significantly affect the technological properties and the efficiency of this connection. The present invention relates to new and valuable compositions, which were not known up to the present time and which can be successfully used as plastic additives, or as gelling agents, thickeners or agents used for other purposes.

Methods of synthesis of diacetate

One of the methods that can be used to obtain diacetate according to the invention described in U.S. patent No. 51106999, Gardlik et al., which is included in the present description by reference.

Methods of obtaining and synthesis of carbohydrates, having chains of different lengths is, described by Kim Gordon, Schmid and Whitesides,Tin and Indium Mediated Allylation in Aqueous Media: Application to Unprotected Carbohydrates,J. Org. Chem., 5500-5507, 58(1993) and in the work Whiteside,Journal of the American Chemical Society,113, 6674-6675 (1991). In the work Whiteside was proposed by the reaction of glucose with allylbromide/tin.

One of the methods that can be used to obtain the starting compounds for the synthesis of compositions required for the implementation of the present invention, described below, in which the carbohydrate may be added allyl group. This is illustrated by the reaction scheme is given only as examples, and such reactions can be carried out for carbohydrates that have a greater or fewer carbon atoms in its chain.

In accordance with the present invention acetylene compound produced by the method comprising (a) reaction of carbohydrate and alkenylphenol group with the first connection; and (b) the reaction of condensation of the specified first connection with aromatic aldehyde with education acatalog connection. In some cases, this Alchemilla group contains allyl.

During the research that led to the creation of one of the embodiments of the present invention, it was found that the above-described chemical reaction with allylbromide/tin one is by one of the methods of synthesis of hydrocarbon chains of carbohydrate, and this reaction can be carried out as one of the stages in the sequence of reactions, which, as it has been unexpectedly discovered, allow to obtain a composition having a number of advantages and valuable properties. The total path of the reaction can be used in various forms for the synthesis of carbohydrates upon receipt of the compositions according to the invention. In one of the embodiments the present invention relates to the use of reactions for the synthesis of carbohydrates in combination with other reactions of formation of acetals to obtain compositions according to the invention.

Can be obtained substituted diacetate, triacetate and monoacetal sorbitol. These structures contain a mixture of acetals any correlated types (such as di-, tri - and/or monoacetal related to the desired acetal). Although the removal of these impurities is not always going to happen (especially if they are present in very low proportions) before the introduction of the specified diacetate, triacetate or monoacetal in the target polyolefin, however, removing these impurities may still be desirable, and such clearance may contribute to increasing the transparency of the resin produced by the above method.

In one of the embodiments of the invention cleanup diacetate can be done by removing any present t is acetale their extraction with the use of relatively non-polar solvent. As one non-limiting example, the removal of impurities can serve as a cleaning product, which resulted in the number of diacetyl in such a composition of the additive is at least 95%, and even up to 98 percent or more, depending on the purpose of the application.
