Abstract: The invention concerns substance mixtures containing: (A) compounds containing vinyl groups; (B) an active amount of a mixture which inhibits premature polymerization of the compounds containing vinyl groups and contains: (i) at least one N-oxyl compound of a secondary amine which does not carry any hydrogen atoms on the .alpha.-carbon atoms; and (ii) at least one iron compound; (C) optionally nitro compounds; and (D) optionally co-stabilizers. The invention further concerns a process for inhibiting the premature polymerization of compounds (A) containing vinyl groups, and the use of mixture (B), optionally mixed with nitro compounds (C) and/or co-stabilizers (D), for inhibiting the premature polymerization of radically polymerizable compounds and for stabilizing organic materials against the harmful effect of radicals.

Abstract: Preparation of guanidine derivatives (I) comprises reacting O-alkylisourea salts (II) with an amine (III) in the presence of seed crystals of (I). Preparation of guanidine derivatives of formula (I) comprises reacting O-alkylisourea salts of formula (II) with an amine of formula (III) in the presence of seed crystals of (I). R1 = 1-8C alkylene or a divalent 5-10C cycloaliphatic group; R2 = H or 1-8C alkyl; or NR1R2 = 5-6 membered ring substituted by Z; Z = COOR3, SO2OR3 or PO(OR3)(OR4); R3 = H, alkalimetal or an equivalent of an alkaline earth metal; and R4 = as for R3 or 1-6C alkyl; R5 = 1-8C alkyl; X = equivalent of an anion.

Abstract: Purification of creatine (I) involves adding the (I) to be purified, in anhydrous form, to a saturated aqueous solution of (I) monohydrate, so that the anhydrous (I) is dissolved with hydration, then separating the crystals of (I) monohydrate which precipitate from the solution. An Independent claim is also included for the preparation of (I) monohydrate, by: (a) reacting sarcosine with an guanylating agent in an aqueous medium, so that crude (I) monohydrate is precipitated; (b) separating the crude product form the medium; (c) optionally washing; (d) converting the product into anhydrous (I); (e) adding the anhydrous (I) to a saturated aqueous solution of (I) monohydrate, so that the anhydrous (I) is dissolved with hydration; (f) separating the crystals of (I) monohydrate which precipitate from the solution; and (g) utilizing the aqueous solution at least partially as aqueous medium in step (a) and/or washing liquid in step (c).

Abstract: Production of a sarcosine solution with a predetermined pH comprises subjecting a crude sarcosine solution to bipolar electrodialysis. Independent claims are also included for the following: (1) an integrated process for producing a sarcosine solution with a predetermined pH, comprising: (i) producing a crude sarcosine solution; and (ii) subjecting the solution to bipolar electrodialysis; (2) an integrated process for producing creatine or creatine monohydrate, comprising performing steps (i) and (ii) as in process (1) and reacting the solution from step (ii) with cyanamide.
