Tridecyl alcohol

The 13—carbon tridecyl alcohol is usually considered to be a plasticizer range alcohol because of its manufacture by the oxo process and its use in making plasticizers. On the other hand, some types of linear 9- and 11-carbon alcohols find major appHcation in detergents. 

Lubricants, Fuels, and Petroleum. The adipate and azelate diesters of through alcohols, as weU as those of tridecyl alcohol, are used as synthetic lubricants, hydrauHc fluids, and brake fluids. Phosphate esters are utilized as industrial and aviation functional fluids and to a smaH extent as additives in other lubricants. A number of alcohols, particularly the Cg materials, are employed to produce zinc dialkyldithiophosphates as lubricant antiwear additives. A smaH amount is used to make viscosity index improvers for lubricating oils. 2-Ethylhexyl nitrate [24247-96-7] serves as a cetane improver for diesel fuels and hexanol is used as an additive to fuel oil or other fuels (57). Various enhanced oil recovery processes utilize formulations containing hexanol or heptanol to displace oil from underground reservoirs (58) the alcohols and derivatives are also used as defoamers in oil production. 

Dibasic Acid Esters. Dibasic acid esters (diesters) are prepared by the reaction of a dibasic acid with an alcohol that contains one reactive hydroxyl group (see Esters, organic). The backbone of the stmcture is formed by the acid. The alcohol radicals are joined to the ends of the acid. The physical properties of the final product can be varied by using different alcohols or acids. Compounds that are typically used are adipic, azelaic, and sebacic acids and 2-ethyIhexyl, 3,5,5-trimethyIhexyl, isodecyl, and tridecyl alcohols. 

Other olefins applied in the hydroformylation process with subsequent hydrogenation are propylene trimer and tetramer for the production of decyl and tridecyl alcohols, respectively, and C7 olefins (from copolymers of C3 and C4 olefins) for isodecyl alcohol production. 

In a patent survey [76] about shampoos over the period 1968-1978 the so-called cryptoanionic alkyl ether carboxylate based on tridecyl alcohol with 6.5 mol EO has been mentioned for a conditioning shampoo in combination with an amphoteric and cationic surfactant [77]. Because of the low interference with cationic surfactants no negative effect on the conditioning properties has been found [78].

The demands for new alcohols were to a considerable extent satisfied by the commercialization of the oxo synthesis in the United States (1). The synthesis involves reaction of an olefin with carbon monoxide and hydrogen to produce an aldehyde, which is reduced subsequently to a primary alcohol. From branched chain feeds such as pentene, heptene, nonene, and tetrapropylene-hexyl, isooctyl, isodecyl, and tridecyl alcohols have been made available to the plasticizer industry in large volume. These alcohols are mixtures of branched chain isomers owing to the branched nature of the olefin feed. (Oxo hexyl alcohol contains about H 1-hexanol). 

Alternate products of a high degree of linearity can be produced by oxonation of linear alpha olefins. By this process, one can obtain alcohols of any desired chain length, including the odd-numbered ones. Except for tridecyl alcohol, odd-numbered alcohols in the plasticizer range are not currently produced in volume at attractive prices in the United States. 

In both cases, commercial products have alkyl chain lengths from 8 to 18 carbons but the ether amine derived products usually have branched alkyl chains as they are produced from fatty alcohols such as 2-ethylhexanol, isodecyl and tridecyl alcohol. Those produced from alkyl amines usually have linear hydrocarbon chains because they are produced from naturally derived fatty acids except when made from 2-ethylhexylamine. 

Dodecene is an intermediate for surfactants, mainly through two routes. One, the larger user, produces dodecylbenzene sulfonate for anionic detergents. The other goes through the oxo process to tridecyl alcohol, which then is converted into a nonionic detergent by the addition of alkylene oxides. 

These show that alkyl chains play an important role in the protein extraction ability. Bulky two-tailed surfactants are favourable in the protein transfer from an aqueous phase into an organic phase, while the other surfactants, having saturated-straight alkyl chains, dioctyl phosphoric acid (DOPA) and dioctyl sulfosuccinate (AOC), or a single alkyl chain, monooleyl phosphoric acid (MOLPA), are limited by their solubility into an organic solvent or their ability to form reverse micelles. A tridecyl group in di-tridecyl phosphoric acid (DTDPA) and di-tridecyl sulfosuccinate (ATR) comes from the tridecyl alcohol which includes several isomers, and therefore these surfactants also have bulky tails.
