Abstract: Precipitation method involves utilizing a non-polar solvent or solvent mixtures. The solution is removed with a polar solvent selectrd from hydroxyl group containing compound, has a general formula (I) and carbonyl group containing compound has general formula (II). The precipitated polymer is isolated. A replacement with the polar solvents and the separation of volatile solution components from the polymers are carried out by degassing in a stirred tank, kneading machine, thin film vaporizer, falling film evaporator or coil tube evaporator. The hydroxyl group containing compound having general formula (I), is R1>(O-A)n-OH. R1>H, 2-20C alkyl or alkenyl residue, 5-20C cycloalkyl residue or 6-20C aryl, alkyl aryl or aryl alkyl residue; A : 2-4C alkylene; and n : 0-10. The carbonyl group containing compound having general formula (II) is R2>-CO-X-R3>. R2>H, 2-20C alkyl or alkenyl residue, 5-20C cycloalkyl residue or 6-20C aryl, alkylaryl or arylalkyl residue; X : S or O and R3>2-20C alkyl or alkenyl residue, 5-20C cycloalkyl residue or 6-20C aryl, alkylaryl or arylalkyl residue.

Abstract: Preparation of polyalkenyl amine comprises reaction of a component comprising at least a simple unsaturated polyalkene with carbon monoxide and hydrogen to give a hydroformylated polyalkene, and reaction of hydroformylated polyalkene with hydrogen and ammonia or an amine having at least a primary or secondary amino group; where before the above steps, polyalkene or hydroformylated polyalkene is dissolved in a first solvent and the first solvent is replaced by a second solvent.

Abstract: A process for extracting hydrocarbons from oil sand, in which the oil sand i s treated in a separation apparatus in at least one process step with a composition which comprises water and a hydrophobin and if appropriate further assistants, lea ds to an improved yield of hydrocarbons.
