Erythromycin, a macrolide antibiotic, lacks a significant chromophore. Detection sensitivity was enhanced by using a wavelength of 200 nm and selecting an injection solvent of lower conductivity than the BGE. In order to facilitate the separation of erythromycin and its related substances, 35% (v/v) ethanol was incorporated into a 150 mM phosphate buffer pH 7.5. Resolution of all of the compounds was achieved in approximately 45 min. The method was employed as an assay method for erythromycin and for impurity determination. Peptide antibiotics, such as colistin and polymyxin, are mixtures of many closely related compounds. A validated CZE method for impurity analysis of polymyxin B was described, employing 130 mM triethanolamine-phosphate buffer at pH 2.5 to reduce the adsorption of analyte onto the capillary wall. Methyl-/l-cyclodextrin (M-/1-CD) and 2-propanol were found to be necessary for selectivity enhancement. Using similar buffer additives, the same group developed and validated a method for colistin analysis. ... 

The water-soluble flume retardants are most easily applied by impregnal-ing the fabric wilh a water solution of a retardant, followed by drying. The water-soluble flame retardants used must widely for textiles are listed in Tahle 3. Less commonly used retardants include sulfamates of urea or other amides and amines aliphatic amine phosphates, such as triethanolamine phosphate, phosphamic acid tamido phosphoric acid. and its... 

Other DCAs introduced in the 1960s included the phosphated hydroxy-amines (hydroxylamine phosphate esters), such as triethanolamine phosphate ester. These are efficient scale inhibitors and are still employed in formulations today, but, like P-PO4, they are also prone to reversion (hydrolysis) to orthophosphates.

This product is a triethanolamine phosphate ester. It is a slightly yellow liquid, relatively thick surfactant which is used in high caustic solutions. 

In order to fix fine silt in the soil one uses a product containing SAS and also anticorrosion and bacteriocidal substances (for example, triethanolamine phosphate and the fluoro-derivatives of ethanolamine and hexane are added to a solution of an organic polymer, with a concentration of 0,2-18%). On spreading this product, a film binding the silt into aggregates is formed so that the silt is not washed away by water [513],...

The rate of stripping or the stripabiUty on cataly2ed urethane and epoxy resin finishes can be increased by adding formic acid, acetic acid, and phenol. Sodium hydroxide, potassium hydroxide, and trisodium phosphate [10101-89-0] may be added to the formula to increase the stripabiUty on enamel and latex paints. Other activators include oleic acid [112-80-17, trichloroacetic acid [76-85-9], ammonia, triethanolamine [102-71-6], and monoethyl amine. Methylene chloride-type removers are unique in their abiUty to accept cosolvents and activators that allow the solution to be neutral, alkaline, or acidic. This abihty gready expands the number of coatings that can be removed with methylene chloride removers. 

For many years such media have been based on strong salt solutions, e.g. calcium chloride brines. Sodium dichromate has been used (seep. 17 26), but recently other inhibitors have been claimed to be effective. One patent quotes N-alkyl-substituted alkanolamines, e.g. 2-ethyl ethanolamine -I- BTA at pH A mixture of hydrazine hydrochloride -i- BTA has been claimed as well as a mixture of gelatin -h triethanolamine -h potassium dihydrogen phosphate . Other examples are to be found in the patent literature and the above are quoted to illustrate the diversity of chemicals that may be used.

Emulsions containing a water-solubile herbicide salt and a herbicide soluble in an organic solvent are prepared by a mixture of water, dioctyl phthalate, and isophorone. In this case ethoxylated poly ary lphenol phosphate neutralized with triethanolamine and ethoxylated acid phosphoric acid esters is used as emulsifier [231],... 

A mixture of monolauryl phosphate sodium salt and triethylamine in H20 was treated with glycidol at 80°C for 8 h to give 98% lauryl 2,3-dihydro-xypropyl phosphate sodium salt [304]. Dyeing aids for polyester fibers exist of triethanolamine salts of ethoxylated phenol-styrene adduct phosphate esters [294], Fatty ethanolamide phosphate surfactant are obtained from the reaction of fatty alcohols and fatty ethanolamides with phosphorus pentoxide and neutralization of the product [295]. A double bond in the alkyl group of phosphoric acid esters alter the properties of the molecule. Diethylethanolamine salt of oleyl phosphate is effectively used as a dispersant for antimony oxide in a mixture of xylene-type solvent and water. The composition is useful as an additive for preventing functional deterioration of fluid catalytic cracking catalysts for heavy petroleum fractions. When it was allowed to stand at room temperature for 1 month it shows almost no precipitation [241].

Different organic and inorganic buffers, such as ammonium acetate, ammonium formate, HEPES, Gly-Gly, and triethanolamine, were selected to study the response of biotin and fluorescein-biotin in MS and compared to phosphate buffer. Biotin and fluorescein-biotin were dissolved in the carrier solution compositions of buffer (10 mM pH 7.5)/methanol (50 50, v/v) at concentrations of 10 ng pl k Both infusion and 20 pl-loop injection experiments were performed with detection by MS in full-scan and SIM mode. Main optimization criteria are the maximum response of biotin and fluorescein-biotin with lowest interference of the carrier solution. HEPES, Gly-Gly, and triethanolamine give very high background response, which significantly hampers the detection of biotin and fluorescein-... 

Fluorhydroxyapatite solid solutions can be prepared by the sol-gel method [134,135]. Cheng et al. reported the control of fluoride content in fluorhydroxyapatite solid solutions by the amounts of triethanolamine (N(CH2CH20H)3) and trifluoroacetic acid (CF3COOH) in the mixed ethanol solutions of Ca(N03)2 and P0(CH2CH20H)x(0H)3 x with a Ca/P ratio of 1.67 [134]. After evaporation of the mixed ethanol solution at 150°C on a hot plate, the powder obtained, comprising a homogeneous mixture of calcium nitrate crystallites and amorphous calcium phosphates, is then heated at 500 or 900°C for 1 h to be transformed into the pure apatitic phase. 

The three major types of raw materials used in superplasticizers, SNF, SMF, and polyacrylates are shown in Fig. 2.1, which also illustrates the three different types of polyacrylates. Minor amounts of other materials are often added such as triethanolamine (to counteract retardation), tributyl phosphate (to cut down excessive air entrainment) and hydroxycarboxylic acid salts or lignosulfonates (to increase retardation). In addition proprietary superplasticizers can be blends of two of the main ingredients.
