Hexahydro-1,3,5-tris -5-triazine

Strong bases, such as potassium acetate, potassium 2-ethylhexoate, or amine—epoxide combinations are the most useful trimerization catalysts. Also, some special tertiary amines, such as 2,4,6-tns(A7,A7-dimethylarninomethyl)phenol (DMT-30) (6), l,3,5-tris(3-dimethylaminopropyl)hexahydro-j -triazine (7), and ammonium salts (Dabco TMR) (8) are good trimerization catalysts. 

The addition of copper to a boiling solution of benzenesulphonyl azide in methanol gave benzenesulphonamide 18 (80%) as the major product together with minor amounts of methylenebis(benzenesulphon-amide) 22 and 1,3,5-tris (benzenesulphonyl) hexahydro-s-triazine 23, resulting from condensation of 18 with the formaldehyde formed in the reaction 33>. Cuprous chloride was even more effective, but cuprous... 

The tris(acryloyl) derivative (R is CH = CH2) was subsequently developed as a fixing agent for use with the Basazol(BASF) dyes in the printing of cellulosic fibres, in conjunction with urea as hydrotrope [444]. It has also been shown [445] that aftertreatment with 1,3,5-tris(acryloyl)hexahydro-s-triazine or the tris ((3-chloropropionyl) derivative improves the wet... 

Modification of poly(carbodiimide) foams with polyols afford hybride foams containing urethane sections. However, the thermal stabilities of the poly (urethane carbodiimide) foams are lower. Using isocyanate trimerization catalysts, such as l,3,5-tris(3-dimethylaminopropyl)hexahydro-s-triazine, in combination with the phospholene oxide catalyst gives poly(isocyanurate carbodiimide) foams with improved high temperature properties. The cellular poly(carbodiimide) foams derived from PMDI incorporate six-membered ring structures in their network polymer structure. ... 

Modification of the poly(carbodiimide) foams, using polyols as comonomers, is possible, but the excellent thermal and flammability properties are reduced. Poly(carbodiimide isocyanurate) foams can also be continuously produced using 1,3,5-tris-(3-dimethylaminopropyl)-hexahydro-s-triazine as the cocatalyst. Other trimerization catalysts, such as potassium 2-ethylhexanoate and quaternary ammonium carboxylate (Dabco TMR 2) are also used as cocatalysts in the formation of poly(carbodiimide isocyanurate)... 

Dimethylamine and trimethylamine (commercially available), 1,3,5-tri-N-methyl hexahydro-5-triazine (from reaction of formaldehyde and methylamine), tetramethylhydiazine (gift of B. J. Aylett), tetramethylmethylenediamine (from reaction of formaldehyde with dimethylamine), dimethyl- and diethylnitrosamine (from reaction of nitrous acid with the appropriate dialkylamine), diethylmethyl-amine (from reductive methylation of diethylamine), ethylethylideneamine (from reaction of ethylamine and acetaldehyde), and TMT and TET (from oxidation of the appropriate wnst/m-dialkylhydrazine). 

An active co-catalyst system was proposed (83). The system is composed of 2,4,6-tris(diethanolamino)-s-triazine and l,3,5-tris(3-dimethylamino i opyl) hexahydro-s-triazine. This catalyst was used to jx-epare rigid carbodiimide foams from TDI without external heating. 

A combination catalyst system comprising 2,4,6-tris(n-methylet-hanolamino)-s-triazine (I), and optionally, l,3,5-tris(3-dimethylaminopropyl)-hexahydro-s-triazine, bis(tributyltin) oxide or bis(triphenyltin) oxide was used for preparing carbodiimide foams. For example, a mixture of 0.5 g (I) and 50 g of tolylene diisocyanate was stirred at lOO C. The foaming started after 9 min and about 1 min after the foaming, the temperature in the vessel rose to 192 C the resulting foam occupied a volume of 800 ml (89, 90). 

Hydrogen sulfide is present in natural gas and it is a highly undesirable constituent. Therefore, several methods for its removal have been developed. One such method is the injection of an aqueous solution of l,3,5-tris(2-hydroxyethyl)-hexahydro-r-triazine 25 into the gas stream (Scheme 2). The main product of this reaction is generally assumed to be... 

To a resin flask are added 30 parts of distilled diisocyanate, 7 parts of ethylene dichloride, 0.2 part siloxane oxyalkylene copolymer, and 0.5 part tris(3-dimethylaminopropyl)hexahydro-s-triazine. The mixture reacts to form a hard, coarse foam of low flammability.

A-(phosphonomethyl) glycine is obtained in a good yield by reacting the sodium salt of tris-(carboxymethyl)-hexahydro-5-triazine with phosphonic acid diesters [83]. 

Trifluoroacetaldehyde figures in recent work on the synthesis of analogues of nitramine-type explosives, having been used to prepare 2,2,2-trifluoro-1,1-dinitraminoethane (20) by application of the route used to procure Medina itself [CHj(NHNOj)2] (Scheme 19), and to obtain the 2,4,6-tris(trifluoromethyl) derivative (22) of RDX (Scheme 20). Nitration of 2,4,6-tris(trifluoromethyl)hexahydro-sym-triazine (21) yields the heterocyclic nitramine (22) directly. The acetamido-analogue [CF3-CH(NH COMe)2] of the bisformamide (19a) can be prepared by heating anhydrous trifluoroacetaldehyde with acetamide, and the trifluoroacetamido-compound... 

There is a significantly prolonged antifungal action obtained in lubricoolants when compared to failure with the tris(2-hydroxyethyl)-derivative although the MIC of the two hexahydro-s-triazines do not differ very much.

Triazines. Certain tiiazines, such as 1,3,5 tri-(2-hydroxyetbyl)-hexahydro-S-triazine, react rapidly with hydrogen sulfide to form water soluble liquid byproducts. A claimed advantage for this type of process is the corrosion inhibition properties of the byproducts. 

The Sulfa-Scrub process utilizes a cyclic polyamine of the triazine class to absorb and react with hydrogen sulfide. The chemical formulas for a specific triazine, 1,3,5 tri-(2 hydroxyethyl)-hexahydro-5-triazine, and products of its reaction with H2S are shown in Figure 16-10. It is reported that the process will also remove mercaptans, but not COS. Advantages claimed for the Sulfa-Scrub process include...
