Abstract: Method for producing tertiary phosphines by reacting a compound of the general formula (I) in which A is R 1 or L 2 , B is R 2 or L 3 , the R 1 and R 2 radicals are each independently an organic radical having in each case from 1 to 30 carbon atoms, where the R 1 and R 2 radicals may also be joined together; and the leaving groups L 1 to L 3 are each independently halogen, alkyloxy having from 1 to 10 carbon atoms or aryloxy having from 6 to 10 carbon atoms (a) with an alkali metal in an organic aprotic solvent and (b) a compound of the general formula (II) L 4 -R 3 (II) in which the R 3 radical is an organic radical having in each case from 1 to 30 carbon atoms; and the leaving group L 4 is halogen, alkyloxy having from 1 to 10 carbon atoms or aryloxy having from 6 to 10 carbon atoms, in which the resulting reaction mixture is hydrolyzed with an aqueous base which has a pH of >= 10 and the organic phase is removed from the aqueous phase.

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: Producing homo- or copolymers with a weight-average molecular weight of 10000-10000000 by polymerizing olefinic monomers having 3, 4, 6-8 or 10-30 carbon atoms and optionally olefinic comonomers having 3-30 carbon atoms in the liquid phase in the presence of an ionic liquid catalyst comprises using a pyrazolium salt (I) as the catalyst. Producing homo- or copolymers with a weight-average molecular weight of 10000-10000000 by polymerizing olefinic monomers having 3, 4, 6-8 or 10-30 carbon atoms and optionally olefinic comonomers having 3-30 carbon atoms in the liquid phase in the presence of an ionic liquid catalyst comprises using a pyrazolium salt of formula (I) as the catalyst. R1>-R3>optionally substituted 1-200C aliphatic, alicyclic or aromatic (hetero)hydrocarbyl, or R3> can be H; A : n-valent anion; n : 1-4. An independent claim is also included for pyrazolium salts of formula (I) with the following definitions. R1>-R3>1-6C alkyl, or R3> can be H; A : aluminate anion (AlX4.mAlX3)->; X : halo; m : 0-1.5.

Abstract: A process for preparing organic chlorides in which the chlorine atom is bonded to a CH 2 group by reacting the corresponding alcohols with thionyl chloride in the presence of a triaylphosphine oxide at a temperature of from 20 to 200° C. and a pressure of from 0.01 to 10 MPa abs, which comprises using the triarylphosphine oxide in a molar ratio to the amount of OH groups to be chlorinated of from 0.0001 to 0.5.
