20110004013 | METHOD FOR PRODUCING DIHYDROXYBENZENE DERIVATIVE - A method of producing a compound represented by the following general formula (3): | 01-06-2011 |
20110230674 | METHOD OF SEPARATING PHENOLIC COMPOUNDS IN SALIFIED FORM - The subject of the present invention is a method for separating phenolic compounds in salified form from a reaction medium comprising them. The method of the invention for separating phenolic compounds in salified form from an aqueous reaction medium resulting from the reaction of a phenolic compound and of glyoxylic acid in the presence of a base leading to a reaction medium comprising at least the excess of initial phenolic compound in salified form and the various mandelic compounds in salified form resulting from the reaction, is characterized by the fact that said reaction medium is brought into contact with a basic anion-exchange resin that leads to the selective attachment of the initial phenolic compound to said resin and to the recovery of an aqueous stream comprising the mandelic compounds in salified form resulting from the reaction, and that the phenolic compound in salified form attached to the resin is separated by a resin regeneration treatment. | 09-22-2011 |
20120238773 | COMPOSITION COMPRISING CAFFEOYLSHIKIMIC ACIDS, PROTOCATECHUIC ACID, HYDROXYTYROSOL, HYDROXYBENZOIC ACID AND THEIR DERIVATIVES AND METHOD OF PREPARATION THEREOF - A composition comprising caffeoylshikimic acids, protocatechuic acid, hydroxytyrosol, hydroxybenzoic acid, said caffeoylshikimic acids and their derivatives extracted from any part of oil palm including but not confined to the vegetation liquor of palm oil milling and palm oil mill effluent, and a method for use in the preparation of a composition containing caffeoylshikimic acids, protocatechuic acid, hydroxytyrosol, hydroxybenzoic acid, said caffeoylshikimic acids and their derivatives.
