Alkyl salicylate

Treating petroleum oils with 3-5% calcium alkyl salicylate and 0.5-3% triethanolamine salts of phosphoric acid esters and ethoxylated dodecyl alcohol increases oxidation-thermal stability at 180-200°C in the manufacture of oil for metal parts quenching. The agent provides also short-term anticorrosion protection of the hardened articles [261]. Phosphoric acid salt alkyl esters are used in anticorrosives and aqueous dispersions in waterborne polyester coatings for metals [244]. 

All commercial materials are based on calcium hydroxide and liquid alkyl salicylates (Prosser, Grolfman Wilson, 1982) and are supplied as a two-paste pack. Zinc oxide is sometimes added to the calcium hydroxide, as are neutral fillers. A paste is formed from this powder by the addition of a plasticizer examples include A-ethyl toluenesulphonamide (o- orp-) and paraffin oil, with sometimes minor additions of polypropylene glycol. The other paste is based on an alkyl salicylate as the active constituent containing an inorganic filler such as titanium dioxide, calcium sulphate, calcium tungstate or barium sulphate. Alkyl salicylates used include methyl salicylate, isobutyl salicylate, and 1-methyl trimethylene disalicylate. An example of one commercial material, Dycal, is given in Table 9.7, but its composition has been subjected to change over the years. 

Prosser, Stuart Wilson (1979) and Prosser, Groffman Wilson (1982) examined the setting of a number of these cements using infrared spectroscopy. The infrared spectrum of the alkyl salicylates showed an O-H stretch band at 3190 cm" and a C-O stretch band at 1675-95 cm" .

On developing easy access to a variety of 6-alkyl salicylic acids, Shirai and co-workers found that the methoxy group of 3-butyl-7-methoxyphthalide (3) was cleanly cleaved during AICI3 (5 equiv.)-promoted displacement with butanethiol at room temperature the product was the phenol 4 [17]. When the reaction was performed at...

It can be seen that acidic dispersants provided positive potentials and that basic dispersants provided negative potentials. This is also true for the work of van der Minne and Hermanie the calcium alkyl salicylate is weakly acidic because of the calcium ions and the quaternary ammonium picrate is weakly basic because of the basicity of the picrate anions.

The hydrolysis of alkyl salicylates often a prolonged process under alkaline conditions can be effected in quantitative yield with trifluoroacetic ackJ. Thus methyl 2-hydroxybenzoate in trifluoroacetic acid (10 moles) sealed in a thick glass tube, after heating at 100°C for 13 hours, gave 2-hydroxybenzoic acid in 100% yield (ref.91).

Setting calcium hydroxide cements are typically based on liquid alkyl salicylates, and they are supplied to the clinician as a two-paste pack [36], Alkyl salicylates that have been used include methyl salicylate, isobutyl salicylate and 1-methyl trimethylene disalicylate [37], These cements set because the alkyl salicylate contains a phenolic -OH group which has acid character, and this means it can react with the alkaline calcium hydroxide [38],...

Higher alkylated phenols are obtained by the interaction of phenol and C16-C18 olefins from wax cracking. The corresponding alkylated salicylic acids (formed by Kolbe-Schmitt carboxylation) are lubricants for diesel engines.
