摘要:
A process for preparing guanidino-functional, free radically polymerizable compounds comprises (a) combining (1) an amine compound comprising (i) at least one primary aliphatic amino group and (ii) at least one secondary aliphatic amino group, primary aromatic amino group, or secondary aromatic amino group, and (2) a guanylating agent; (b) allowing or inducing reaction of the amine compound and the guanylating agent to form a guanylated amine compound; (c) combining (1) the guanylated amine compound, and (2) a reactive monomer comprising (i) at least one ethylenically unsaturated group and (ii) at least one group that is reactive with an amino group; and (d) allowing or inducing reaction of the guanylated amine compound and the reactive monomer to form a guanidino-functional, free radically polymerizable compound.
摘要:
The present invention is directed to a method for preparing a cyclic guanidine comprising reacting (i) a cyanamide, (ii) a polyamine, and (iii) a weak acid. The present invention is also directed to a coating composition comprising the cyclic guanidine.

Verfahren zur Herstellung von Kreatin oder Kreatin-monohydrat, wobei man Cyanamid mit Natrium- oder Kaliumsarkosinat in Wasser oder einem Gemisch aus Wasser und einem organischen Lösemittel bei einer Temperatur von 20 bis 150°C und einem pH-Wert von 7,0 bis 14,0 umsetzt. Auf diese Weise läßt sich Kreatin bzw. Kreatinmonohydrat in guten Ausbeuten von 60 bis 90 Gew.-% und in sehr hoher Reinheit herstellen.
摘要:
The present invention refers to a method for increasing the guanidine carbonate yield in a combined melamine low pressure process (10) and guanidine carbonate treatment process (20) by adding cyanamide and/ or dicyandiamide to a) a melamine mother liquor (MML) obtained in the melamine low pressure process (10), and/or b) a guanidine carbonate mother liquor (GCML) obtained in the guanidine carbonate treatment process (20), and /or c) a mixture of a melamine mother liquor (MML) and a guanidine carbonate mother liquor (GCML).
wherein R 1 is selected from hydrogen, alkyl, aryl, and combinations thereof, R 2 is selected from hydrocarbylene, heterohydrocarbylene, and combinations thereof, each R 3 is independently selected from hydrogen, hydrocarbyl, heterohydrocarbyl, and combinations thereof, R 4 is selected from hydrogen, hydrocarbyl, heterohydrocarbyl, and combinations thereof, R 5 is selected from hydrocarbylene, heterohydrocarbylene, and combinations thereof, with the proviso that R 2 and/or R 4 comprise(s) at least one aromatic moiety
摘要:
The present invention relates to a process for the preparation of the compound N-(3,5-dimethylphenyl)-N'-(2-trifluoromethylphenyl) guanidine of formula (I) which comprises reacting a salt of a compound of formula (II) or a mixture of the salt of the compound of formula (II) and a compound of formula (II) with a compound of formula (III), in the presence of a polar organic solvent; a crystalline solid form of the compound of formula (I), in particular crystalline solid form A; to a pharmaceutical composition comprising them; and to their use as a medicament, in particular to the treatment of a condition mediated by Rho-GTPase cell proteins.
