Abstract: PROBLEM TO BE SOLVED: To easily and safely produce the subject compound useful as a production intermediate for a metallocence complex known as a polymerization catalyst in one step by reacting two specific kinds of compounds in the presence of a Friedel-Crafts catalyst. SOLUTION: The objective substituted indanone of the formula IV or the formula V is produced by reacting a compound of the formula I or the formula II [R , R , R and R are each H, a 1-4C (fluoro)alkyl, a (1-4C alkyl)silyl, phenyl, benzyl or R and R form a benzene ring together with the bonded C atom] with a compound of the formula III [R so a 1-10C alkyl or a (1-4C alkyl- substituted)phenyl; X is Cl, Br or I] in the presence of a Friedel-Crafts catalyst (e.g. AlCl3 ) in a Friedel-Crafts solvent (e.g. methylene chloride) at -80 to 0 deg.C.

Abstract: The invention relates to a thermoplastic polymer mixture containing m, m representing a natural number higher than 1, polymers Pn wherein n represents a natural number between 1 and m, and at least one recurring functional group contained in the Pn polymer chain, said group(s) having the structure -(R )x-C(O)-(R )y- wherein x and y independently represent 0 or 1, and x + y = 1, and R , R independently represent oxygen or nitrogen linked into the main polymer chain. The polymers Pn differ in terms of at least one characteristic related to molecular weight. The polymer mixture has a number average molecular weight Mn(P)1, a weight average molecular weight Mw(P)1, a Z average molecular weight Mz(P)1, a heterogeneity index Mw(P)1/Mn(P)1 and a molecular weight Mp(P)1 defined according to DIN 55672-2 in hexafluoroisopropanol as an elution agent. After maintaining the polymer mixture at the melting point of the same, defined according to ISO 11357-1 and 11357-3, for five minutes, the polymer mixture has a number average molecular weight Mn(P)2, a weight average molecular weight Mw(P)2, a Z average molecular weight Mz(P)2, a heterogeneity index Mw(P)2/Mn(P)2, and a molecular weight Mp(P)2 defined according to DIN 55672-2 in hexafluoroisopropanol as an elution agent. The values Mn(P)2, Mw(P)2, Mz(P)2, Mw(P)2/Mn(P)2 and Mp(P)2 lie within the triple replication standard deviation sigma (r) in relation to Mn(P)1, Mw(P)1, Mz(P)1, Mw(P)1/Mn(P)1 and Mp(P)1 according to DIN 55672-2 in hexafluoroisopropanol as an elution agent.

Abstract: Very pure riboflavin (I) is obtained by a process in which the riboflavin is dissolved in dilute aqueous alkali metal hydroxide solution, if necessary the alkaline solution is purified by treatment with active carbon or with a solvent which is insoluble or only slightly soluble in water, the resulting alkaline solution of I is introduced into water which is at 90 DEG -100 DEG C. and to which an acid has been added in an amount such that the reaction mixture is brought to a pH of from 6.5 to 0.8, the temperature being maintained at from 40 DEG to 100 DEG C., the reaction mixture is kept at from 90 DEG to 100 DEG C. for from 10 to 80 minutes and cooled, and I is then isolated.
