| | Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine Usage And Synthesis |
| Description |
Grotan BK is a triazine derivative contained in cutting fluids. It is a formaldehyde releaser. Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine is a light-yellow liquid. It is a formaldehyde condensate product that is used as an antimicrobial agent in metal working fluids.
| | Chemical Properties | Light Yellow Solid | | Uses | Hexahydro-l,3,5-tris-(2-hydroxyethyl)triazin is used in organic synthesis; as a bactericide in cooling fluids and various cosmetic products; formaldehyde liberator. | | General Description | Viscous yellow liquid. | | Air & Water Reactions | Water soluble. | | Reactivity Profile | Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine is an amine and an alcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. | | Health Hazard | Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine (TA, CAS 4719-04-4) is a widely used biocide added to water-based metalworking fluids (MWF) to control microbial populations. However, uncontrolled concentrations of this biocide within metalworking fluids may induce allergic pneumonitis. The mechanism may involve TA eliminating other competing microorganisms while simultaneously inducing the emergence of biocide-resistant mycobacteria, leading to their excessive proliferation within the fluid's sedimentation tanks [6]. Furthermore, TA rapidly releases formaldehyde in diluted aqueous solutions. This substance exhibits strong irritant and corrosive effects on rabbit skin, eyes, and upper respiratory tract, attributed to the formation of irritant formaldehyde and 2-aminoethanol. As formaldehyde is released from TA, this substance is classified as a Category 4 carcinogen alongside formaldehyde. The aerosol form of TA is classified as a Category 2 carcinogen. As no data currently exist on the systemic bioavailability of TA released through hydrolysis in tissues, nor is there experimental evidence indicating formaldehyde reaches germ cells, TA has been categorised as a Category 3B germ cell mutagen. Skin contact is not anticipated to contribute significantly to systemic toxicity[7]. | | Fire Hazard | Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine is probably combustible. | | Flammability and Explosibility | Not classified | | Contact allergens | Grotan BK is a triazine derivative contained as a bio cide in cutting fluids. It is a formaldehyde releaser.
Dermatitis, delayed-type allergic conjunctivitis, and
asthma were described. | | Synthesis | General procedure for the synthesis of hydroxyethyl hexahydrohomotriazine from formaldehyde and 2-aminoethanol: To 6.1 g (0.1 mol) of 2-aminoethanol was added 3.0 g (0.1 mol as formaldehyde) of a 20 mL methanol solution of paraformaldehyde, and the mixture was stirred for 48 h at room temperature. Upon completion of the reaction, the solvent was removed by rotary evaporator and the residue was distilled under reduced pressure to give 6.3 g (86% yield) of light yellow viscous liquid. The physicochemical properties of the obtained compound (I) were in accordance with the data reported in literature [9]. | | Toxics Screening Level | The initial threshold screening level (ITSL) for 1,3,5-triazine-1,3,5(2H,4H,6H)-triethanol (CAS
# 4719-04-4) is 0.015 μg/m3 with an annual averaging time. | | References | [1] Helvetica Chimica Acta, 2007, vol. 90, # 9, p. 1765 - 1780
