A composition, which is suitable for the production of stilbene compounds, can be separated from tall oil. It contains esters of pinosylvin or pinosylvin derivatives and it is concentrated in relation to these. Preferably, the composition contains esters of pinosylvin monomethyl ethers, the acid part of which is formed of an inorganic acid or an organic acid, in particular an organic acid, which is present in the crude tall oil or which is generated from this oil during the process of refining it. Typically, such acids are fatty and resin acids and lower alkane acids. With the invention, it is possible to generate, at an industrial scale, product fractions, and the pinosylvin compounds which are separated from the fractions can be used as such or they can be further modified by means of different chemical methods.
A composition suitable for manufacturing stilbene compounds, which comprises esters of pinosylvin and that it is enriched in relation to these, wherein the acid part of said esters is derived from linoleic acid, linolenic acid, oleic acid, or a tricyclic, aliphatic or aromatic carboxylic acid.
A method of producing a composition suitable for manufacturing pinosylvin and its compounds, said method comprises recovering a fraction of the distillation or evaporation of crude tall oil as the overhead product of a column or of an evapopration used in the distillation of tall oil, wherein said fraction contains esters of pinosylvin or its derivatives, which fraction is then enriched in relation to the esters of pinosylvin or its derivatives and wherein stilbene compounds, which form part of the overhead product, are esterified with lower alkane acids or fatty acids or resin acids, or the stilbene compounds are modified by means of chemical technology methods to form compounds that are easier to separate from the rest of the fraction then is the original compound.
A resin acid ester of pinosylvin or of us monomethyl ether wherein the acid part is derived from abietic acid, dehydroabietic acid, neoabietic acid, palustrene acid, pimaric acid or levopimaric acid.
A composition suitable for manufacturing stilbene compounds, which comprises 5 to 95 weight % of esters of pinosylvin, wherein the acid part of said esters is derived from linoleic acid, linolenic acid, oleic acid, or a tricyclic, aliphatic or aromatic carboxylic acid.
