Aluminium glycinate

Back titration with EDTA is used in the pharmacopoeial assays of aluminium glycinate, aluminium hydroxide, aluminium sulphate, calcium hydrogen phosphate. 

Ke and Regier [71] have described a direct potentiometric determination of fluoride in seawater after extraction with 8-hydroxyquinoline. This procedure was applied to samples of seawater, fluoridated tap-water, well-water, and effluent from a phosphate reduction plant. Interfering metals, e.g., calcium, magnesium, iron, and aluminium were removed by extraction into a solution of 8-hydroxyquinoline in 2-butoxyethanol-chloroform after addition of glycine-sodium hydroxide buffer solution (pH 10.5 to 10.8). A buffer solution (sodium nitrate-l,2-diamino-cyclohexane-N,N,N. AT-tetra-acetic acid-acetic acid pH 5.5) was then added to adjust the total ionic strength and the fluoride ions were determined by means of a solid membrane fluoride-selective electrode (Orion, model 94-09). Results were in close agreement with and more reproducible than those obtained after distillation [72]. Omission of the extraction led to lower results. Four determinations can be made in one hour. 

The homogenization of liver, kidney, and muscle tissues with glycine-hydrochloric acid buffer was presented for the determination of OTC, TC, and CTC. The supernatant was purified on a cyclohexyl SPE cartridge previously activated with MeOH and water. The TCs were eluted with MeOH, which was evaporated at 65°C, and the residue was dissolved in mobile phase. Recoveries were achieved greater than 70% in muscle at the MRL concentrations and higher than 60% for kidney with RSD <11%. Gradient elution was employed to improve the separation of OTC and TC from interference found in kidney samples. The eluate from HPLC was mixed with aluminium chloride solution in a low-volume T-piece and delivered into the PTFE tubing 13.7 m X 0.3 mm immersed in an oil bath at 60°C followed by fluorescent detection (22).

Clear antiperspirants have become popular because they leave no visible residue.They are not always formulated through a microemulsion route. Clear sticks can be based on dibenzylidene sorbitol acetal (DBSA) gelling agent and zirconium or glycine-complexed aluminum chlorhydrate antiperspirant actives that are soluble in propylene glycol without water. An alternative route is to closely match the refractive indices of the oil and water phases so a clear product (not a microemulsion) results for an antiperspirant gel [20,23]. Clear deodorant sticks with the active ingredient triclosan can be solidified with sodium stearate, which is incompatible with antiperspirant active ingredients (aluminium chlorhydrates). 

There has been a review of asymmetric Friedel—Crafts reactions. It has been shown that the rhodium-catalysed reaction of potassium phenyltrifluoroborate with A-tosyl ketimines may lead to products such as (18) with high enantioselectivity. (g) The reaction of A-t-butanesuUinylimino esters with arenes to give products (19) is catalysed by Lewis acids, such as indium triflate, and may lead to enantio-metrically enriched a-glycines. The intramolecular alkylation of hydrogenated 0 tetralins, shown in Scheme 2, using iron(III) or aluminium(III) catalysts yields cis-hexahydrobenzophenanthridines. Formation of a stabilized carbocation intermediate is...
