Synthetic Route of 112-70-9, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 112-70-9, name is 1-Tridecanol. This compound has unique chemical properties. The synthetic route is as follows.
EXAMPLE 1 [00073] The following Example describes the condensation esterification of DDDA using Fascat 2003 catalyst, a tin-based esterification catalyst from Elf Atochem, and the preparation of DDDA diesters with varying mole percent Telomer alcohol and Exxal 13. [00074] Reaction mixtures were prepared in 20 mL vials with the compositions indicated in table 4 below. One drop of Fascat 2003 (a product of Atochem) was added to each vial, and the reactions were heated at 200-250 C. for about 12 hours under a nitrogen sweep to remove evolved water. GC analysis of the reaction mixtures showed the expected three component ester mixture: RfO(O)C-(CH2)x-C(O)ORf; RhO(O)C-(CH2)x-C(O)ORh; and RhO(O)C-(CH2)x-C(O)ORf. The actual amount of each ester component present varied as expected with the relative amounts of Telomer alcohol and Exxal 13 present in the synthesis mixture. The appearance of the mixture formed from the respective additive and 150N oil as well as the solubility of the additive in 150N oil are also summarized in the Table 4. It is noteworthy that the fully fluorinated diester, vial 8, was more soluble when heated, but that the solution cooled to a gel-like state as the diester reprecipitated with cooling. Such behavior is very undesirable in a lubricant. This illustrates an important deficiency of the fully fluorinated diesters, since lubricants are often subjected to temperature cycling, and low-temperature performance is often critical.[TABLE-US-00005] TABLE 4 DDDA diesters with Telomer alcohol and Exxal 13 mol % Telomer Solubility in TelomerExxalalcohol 150 N DDDAalcohol13vs total oil atNo.(mmol)(mmol)(mmol)alcoholAppearance25 C. 15.150.2910.743liquid20%24.940.5810.515liquid35.151.349.8812honey->1% like45.052.48.8121very thick oil55.054.46.6240grease0.5% like65.135.625.4751grease?0.25% like75.158.262.7875beeswax like85.3411.060100paraffin0.1% like [00075] Wear test results for some of the above materials are shown in FIG. 2. It is clear from this figure that most of the wear benefit is achieved with only about 20 mole % Telomer alcohol in the diester. The wear response, quite surprisingly, is extremely non-linear. This is contrary to the linear response that might be expected if the wear-reducing effects were simply the net average from the concentration present of completely fluorinated diester (100% Telomer alcohol) and non-fluorinated ester (0% Telomer alcohol). This implies that the non-symmetric, partially fluorinated diesters of the present invention have better wear reducing properties than either the non-fluorinated or completely fluorinated diesters.
According to the analysis of related databases, 112-70-9, the application of this compound in the production field has become more and more popular.
