摘要： The present invention relates to a method and an arrangement for recovery of at least one organic acid from a dilute aqueous solution thereof. In this method a complex between said organic acid and an extractant is formed by contacting the solution with a reactive extractant and dissolving the formed complex into said extractant thus forming an extractant phase. The organic acid is removed from the formed complex by esterification using an alcohol.

摘要： The invention relates to a process for the recovery of formate salt from biomass and the product obtained thereof. Aqueous liquid mixture containing levulinic acid, formic acid and possibly furfural is subjected to a liquid-liquid extraction step, followed by the recovery of furfural, formate salt and levulinic acid or levulinate salt.

摘要： The invention relates to a method for dissolving cationic starch. In the method is obtained an aqueous polyelectrolyte solution comprising a synthetic cationic polymer, which has a charge density value of at least 0.1 meq/g, determined at pH3, the concentration of the cationic polymer in the polyelectrolyte solution being > 2.5 weight-%, and the aqueous polyelectrolyte solution is brought together with cationic starch having a degree of substitution, DS, > 0.1. The cationic starch is dissolved to the polyelectrolyte solution by heating and/or mixing. The invention relates also to a papermaking agent comprising 2 – 40 weight-% of synthetic cationic polymer which has a charge density value of at least 0.1 meq/g, determined at p H 3, and 2.5 – 25 weight-% cationic starch having degree of substitution, DS, > 0.1. The papermaking agent is in slurry form and has a viscosity of 50 – 20 000 m Pas, measured at 25°C with Brookfield DVI+ viscometer.

摘要： The invention relates to a gypsum product which consists of essentially intact crystals having a size of between 0.1 and below 2.0 μm. The product is especially suitable as a coating pigment or filler in paper manufacture. The invention also relates to a process for the preparation of a gypsum product, wherein calcium sulphate hemihydrate and/or calcium sulphate anhydrite, water and a crystallization habit modifier are contacted so that the calcium sulphate hemihydrate and/or calcium sulphate anhydrite and the water are reacted with each other and form a crystalline gypsum product. The calcium sulphate hemihydrate and/or calcium sulphate anhydrite is/are used in such an amount that the reaction mixture formed from the calcium sulphate hemihydrate and/or calcium sulphate anhydrite, the water and the crystallization habit modifier has a dry matter content of between 50 and 84 % by weight. Then, said gypsum product can be formed which consists of essentially intact crystals having a size of between 0.1 and below 2.0 μm.
