Triethanol amine

To avoid this reaction during storage, VEs are often stabilized using small amounts of bases such as triethanol amine. 

Several articles [7,8] have reported that a persulfate-amine system, particularly persulfate-triethanol amine and persulfate-tetramethylethylenediamine (TMEDA) can be used as redox initiators in aqueous solution polymerization of vinyl monomers. Recently, we studied the effect of various amines on the AAM aqueous solution polymerization and found that not only tertiary amine but also secondary and even primary aliphatic amine and their polyamines can promote the vinyl polymerization as shown in Table 6 [40-42]. 

Ethylene-acrylic acid copolymer neutralized with amines such as triethanol amine or N-methyl diethanol amine enhances anti-settling properties [1198, 1554]. 

In the case of esters from, for example, neopentylglycol, pentaerythrite, and trimethylolpropane with fatty acids, tertiary amines, such as triethanol amine, together with a mixture of fatty acids, improve the efficiency [74].

LAB is sulfonated in the para position and the resulting sulfonic acid is then neutralised with caustic soda to produce the sodium salt, which is the most widely used form of LAS worldwide. Other salts such as ammonia and triethanol amine are also used, although in substantially lower amounts compared with NaLAS. 

Decomposition of iron chelates (e. g. Fe-EDTA or a solution of Fe salt in the presence of triethanol amine) in alkaline media (pH >12) in an autoclave for one hour (Sapieszko and Matijevic, 1980). 

After a single application of [ CJtriethanolamine for 48 h to the skin of rats (1000 mg/kg bw 1.75 cm area) and mice (2000 mg/kg bw 1.75 cm area), the absorption rate through rat skin (2.4 mg/cm /h) was estimated to be greater than that through mouse skin (0.4 mg/cm /h). This was evaluated by analysis of [ C]triethanol-amine-equivalents in the blood. The sixfold difference in the absorption rates was explained by the sixfold higher concentration of triethanolamine applied to rat skin rather than by a greater permeability ( p) of rat skin, since the values for rats (1.85 X 10 cm/h) and mice (1.8-2.0 x lO cm/h) were similar (Waechter Rick, 1988, cited in Knaak et al, 1997). Triethanolamine thus enhances its own penetration. 

About 60% of the radioactivity in [I CJtriethanolamine applied to mouse skin (1000 mg/kg bw) was excreted in 48 h in urine and 20% in faeces, with less than 10% found in the skin at the site of application. The biotransformation of [ C]triethanol-amine to monoethanolamine and diethanolamine was specifically investigated in mice after both intravenous and dermal treatments. Neither of the hypothetical metabolites...

Irradiation of the Q band causes alu (it) - eg (n ) electron excitation in M(Pc), and the excited species catalyzes an electron transfer reaction between a donor-acceptor pair such as triethanol-amine-methylviologen. There are two possible pathways and the course of electron transfer is determined by the redox potentials of the components. These processes are quenched by intersystem... 

The ASTM distillation flash char test provides a good indication of both esters and heavy polymers in the reactor effluent. The addition of water dispersible filming amine corrosion inhibitors into the fractionator overhead vapor lines and the addition of mono- and triethanol amines into the feed line of the fractionators has aided in many cases.

Following similar principles of combining the aggregate-forming properties of bifunctional molecules with low cost and low toxicity, a mesoporous silica material with a three-dimensional worm-like pore system was reported. Triethanol amine (TEA) was used as the SDA and TEOS as the silica source in this mesoporous silica, TUD-1.[48] The formation mechanism is depicted in Figure 1.3(a). The properties of the material can be easily tuned by modifications in the synthesis procedure, for example, the pore size of the material was found to be proportional to...
