The present invention relates to novel hardeners for curing epoxy resins and to cure accelerants for the accelerated curing of epoxy resins comprising, in each case, at least one compound from the group of esters of phosphorus-containing acids according to Formula (I), wherein there applies to Formula (I): wherein there applies to the radicals R, R, R, R, X and indices m, n, p, simultaneously or independently of one another:

Hardener and cure accelerant with flame retardancy effect for curing epoxy resins (II)

The invention relates to the use of bis- or multifunctional N,N'-(dimethyl) urons as curing agents for curing epoxy resin compositions in a controlled manner.

Use of N,N'-(dimethyl) urones and method for curing epoxy resin compositions

The present invention relates to novel high-latency liquid hardeners for hardening of curable polymer resins, especially epoxy resins, and to epoxy resin compositions comprising liquid hardeners for the production of fiber composite materials.

High-latency hardeners for epoxy resins

The invention relates to the use of alkyl or dialkyl-semicarbazone as a hardener for hardening epoxy resin and to a method for controlling the hardening of epoxy resin and epoxy resin compounds.

Alkyl or dialkyl-semicarbazone as a hardener for epoxy resin

The present invention relates to new mixtures containing cyanamide and a urea derivative, to liquid curing agents for curing polymer resins, in particular epoxy resins, and to epoxy resin compositions comprising liquid curing agents for producing fibre composite materials.

Curing agents for epoxy resins

The present invention relates to novel latent curing agents for curing curable polymer resins, in particular epoxy resins, and to epoxy resin compositions and the use thereof in the production of fiber composites.

Liquid hardeners for hardening epoxide resins (I)

The present invention relates to novel liquid hardeners for hardening hardenable polymer resins, particularly epoxide resins, and epoxide resin compositions and to the use thereof for producing composite fiber materials.

Liquid hardeners for hardening epoxide resins (II)

The present invention describes guanidine derivatives of the general formula (I) having the stated meanings for the residues R, Rand Ras accelerators for cold-curing epoxy resin compositions. The curing of cold-curing epoxy resin systems may advantageously be accelerated with the assistance of these compounds.

Use of guanidine derivatives as curing accelerators for epoxy resins

The use of guanidinoacetic acid and/or salts thereof in combination with choline and/or betaine to produce an agent for improving brain function, bone growth and the mineralization of bones, for improving cartilage growth, for alleviating aging processes, for strengthening the immune system, as an antioxidative and neuroprotective agent, for lowering the cholesterol and triglyceride value, for preventing inflammatory processes and for lowering the blood sugar level in humans and vertebrates is described. In this connection it has surprisingly turned out that the new agents have a considerably higher bioavailability and are thus better taken up into the cells than was previously known when using creatine.

Use of guanidinoacetic acid (salts) combination with betaine and/or choline to produced an agent that is beneficial to health

The invention relates to the use of aqueous guanidinium formiate solutions, optionally combined with urea and/or ammonia and/or ammonium salts, for the selective catalytic reduction of nitrogen oxides using ammonia in exhaust gases of vehicles. The inventive guanidinium formiate solutions enable a reduction of the nitrogen oxides by approximately 90%. Furthermore, said guanidinium formiate solutions can enable an increase in the ammonia forming potential from 0.2 kg, corresponding to prior art, up to 0.4 kg ammonia per liter of guanidinium formiate, along with freezing resistance (freezing point below &#x2212;25&#xb0; C.). The risk of corrosion of the inventive guanidinium formiate solutions is also significantly reduced compared to that of solutions containing ammonium formiate.

Use of aqueous guanidinium formate solutions for the selective catalytic reduction of nitrogen oxides in exhaust gases of vehicles

The present invention provides new addition compounds of guanidinoacetic acid with malic acid, aspartic acid, ascorbic acid, succinic acid, pyruvic acid, fumaric acid, gluconic acid, alpha-ketoglutaric acid, pyroglutamic acid, 3-nicotinic acid, lactic acid, citric acid, maleic acid, acetic acid, formic acid, 2-hydroxybenzoic acid, L-carnitine, acetyl-L-carnitine, taurine, betaine, choline, methionine and lipoic acid as well as in the form of sodium, potassium or calcium guanidinoacetate. These addition compounds have improved physiological and therapeutic properties and are particularly suitable for use as dietary supplements, as animal feeds and in cosmetic or dermatological preparations in which especially the marked stability and good bioavailability of the addition compounds come to the fore.

Addition compounds of guanidinoacetic acid

The present invention relates to the use of guanidinoacetic acid and/or salts thereof as feed additive, in predominantly vegetarian diets, in particular use being made of salts with hydrochloric acid, hydrobromic acid and phosphoric acid. The use proceeds especially in individual doses from 0.01 to 100 g/kg of feed in the form of powders, granules, pastilles or capsules, the feed additive also being able to be used in combination with other physiologically active materials of value. The claimed use which is suitable especially for breeding and growing livestock, has recourse to a compound which is in particular stable in aqueous solution, can be converted to creatine under physiological conditions, and, in contrast to other guanidine derivatives, is completely available to physiological sectors of use.

Guanidino acetic acid used as an animal food additive

The invention is directed to an improved, reliably performable process for preparing triallyl isocyanurate (TAIC) by Cu-catalysed rearrangement of triallyl cyanurate (TAC) at at least 90&#xb0; C. According to the invention, TAC and, if required, also a Cucatalyst and solvent are fed continuously to a start reaction mixture after onset of the initially inhibited isomerization reaction, the isomerization is performed at from 90 to 160&#xb0; C. and an amount of reaction mixture equivalent to the amount of reactant is drawn off continuously and sent to the workup. Preference is given to effecting the isomerization in TAIC as the reaction medium.

The present invention provides new salts and/or addition compounds and/or complex compounds of guanidinoacetic acid with malic acid, aspartic acid, ascorbic acid, succinic acid, pyruvic acid, fumaric acid, gluconic acid, &#x3b1;-ketoglutaric acid, oxalic acid, pyroglutamic acid, 3-nicotinic acid, lactic acid, citric acid, maleic acid, sulfuric acid, acetic acid, formic acid, 2-hydroxybenzoic acid, L-carnitine, acetyl-L-carnitine, taurine, betaine, choline, methionine and lipoic acid as well as in the form of sodium, potassium or calcium guanidinoacetate. These salts have improved physiological and therapeutic properties and are particularly suitable for use as dietary supplements, as animal feeds and in cosmetic or dermatological preparations in which especially the marked stability and good bioavailability of the salts come to the fore.
