    Abstract: PROBLEM TO BE SOLVED: To produce 2,2'-bis(4-hydroxyphenyl)propane in high yield by adding water to the reaction mixture and reacting phenol with a carbonyl compound in the presence of an organopolysiloxane containing sulfonate group and mercapto group or an inorganic carrier material modified by the sulfonate group and the mercapto group. SOLUTION: A compound of formula I (R to R are each H, a 1-4C alkyl, etc.), (e.g. phenol) is reacted with a compound of formula II (R and R are each H, a 1-6C alkyl, etc.), (e.g. formaldehyde) in the presence of an organopolysiloxane containing sulfonate group and mercapto group by allowing the reaction mixture to include 0.1-30wt.% water, preferably at 50-70 deg.C to provide the objective compound of formula III. This method is useful for producing highly pure bisphenol A having high isomer ratio of a p, p-product/an o, p- product.

    Abstract: The invention relates to shaped polymeric complexes of metals from sub-group 8 of the Periodic Table with ligands of an organosiloxane copolycondensate (random, block or mixed) which is optionally crosslinked by means of Si-, Ti-, Zr- and/or Al-containing crosslinking agents. This copolycondensate comprises units … … and … …… where R - R are … …… in which R is directly P- or N-bonded C1-C10-alkylene, C5-C8-cycloalkylene or … …. The ratio between the number of moles of units (II) and the number of moles of bonded metal atoms is from 1:1 to 1000:1, and the ratio between the units (I) and (II) is preferably from 5:95 to 95:5 mol%. … The polymeric complex compounds are in macroscopic form as spherical particles having a diameter of from 0.01 to 3.0 mm, a BET surface area of from >0 to 1000 m /g, a specific pore volume of from 0.01 to 6.5 ml/g and a bulk density of from 50 to 1000 g/l. … The invention also relates to a number of preparation processes for the substances according to the invention with specific aftertreatment steps, and the use of the polymeric metal complexes as catalysts in organic chemistry.

    Abstract: Rhodium-contg. organopolysiloxane-ammonium cpds. (I) are based on units of formula (R1R2R3R4N+)nXn- (II) R1, R2, R3 = R5SiO3/2 (III) (same or different), with R5 = 1-10C alkylene, 5C, 7C or 8C cycloalkylene, -(CH2)0-6-cyclohexylene-(CH2)0-6- or -(CH2)0-6-C6H4-(CH2)0-6-; free O valencies are satd. either by Si or (III) or by crosslinking units of formula MO4/2, MR'O3/2, M(R')2O2/2 (M = Si or Ti), or AlO3/2 or AlR'O2/2 (with R' = Me or Et; ratio between Si atoms in (III) to bridging Si, Ti or Al from 1:1 to 1:10); R4 = H, 1-8C alkyl, 5-8C cycloalkyl, or benzyl Xn- = (Rh(CO)2I2)-, (RhCl6)3- or (RhCl5)2-, and Cl-, Br-, or I- present in addn. as necessary. (I) are mfd. by partial or complete anion exchange reaction of (II; Xn- = Cl-, Br- or K-) with Na3RhCl6, corresp. K or NH4 cpds., or (NH4)2RhCl5, or free acids, in water or suitable solvent, sepn. of Rh cpd., drying at room temp. -200 deg.C under inert gas or vacuum, classifying, and tempering at 150-250 deg.C. (I) with Xn- = (Rh(CO)2)2- are mfd. by reaction of these prods. with CO at 60-200 deg.C and 1-200 bar in the presence of water, 1-10C alkyl iodide, I2 or HI; or by direct reaction of the above Rh cpds. and others (17 cpds. listed) with CO at same temp. and pressure in the presence of water, etc. (as above) and of (II; Xn- = Hal-); prod. is worked up, etc. as above.
