Nj Pri segrevanju ali oksidiranem . zgorevanje oddaja dražilni dim, zato je treba paziti, da se izognete stiku z oksidanti. Kot olefinska spojina, ki vsebuje štirinajst ogljikovih atomov, ima 1- tetradecena visoko stopnjo molekularne nenasičenosti in reaktivnosti in je pomemben vmesni vmesnik v organski sintezi.

(1) 2- acrylamido-tetradecanesulfonsko kislino je mogoče sintetizirati z akrilonitrilom, 1- tetradecena in fuming žveplove kisline kot surovine v prisotnosti ustreznega količine dehidrirajočega agenta . nuclear magnetic resonance and elemental analysis. The results showed that the molecule contains "C=C", a hydrophobic long-chain alkyl group and a hydrophilic amide group and sulfonic acid group, and has the structural characteristics of a surfactant [1]. Acrylamide and acrylic acid are used as raw materials, dissolved in deionized water, adjusted to pH 6.5-7.5 with NaOH aqueous solution, added with the above-prepared 2-acrylamido-tetradecane sulfonic acid and sodium dodecyl sulfate, stirred and dissolved, nitrogen deoxygenated for 0.5h, then added with ammonium persulfate and sodium bisulfite, reacted in a water bath at 35℃for 2h, and vacuum dried to obtain a hyperbranched hydrophobic associating polymer. The method is simple to operate, efficient, high in product yield, good in viscosity increasing performance, critical associating concentration of 750mg/L, good in temperature resistance, and still has a viscosity retention rate of 62,2%, ko se segreje na 85 stopinj.
(2) V vodni raztopini N, N-dimetilacetamid (DMA), paladijev klorid (PDCL2) kot katalizator in bakreni klorid (cucl2) kot so-katalizator lahko katalizacijo selektivnega oksidacije 1- tetradekena do 2- tetradeka 93%.
(3) nj Anhidrid, izopentanol polioksietilen eter, metil alil polioksietilen eter itd. of concrete components and the generation of cracks. In other words, the water reducer can improve the early strength and meet the requirements of high-strength concrete. At the same time, it has a high water reduction rate, a low addition amount, good dispersion stability, no water seepage and stratification, and does not affect the strength of concrete.
(4) 1-Tetradecene can be used as a pore expander to prepare mesoporous zirconia film. The whole process adopts a simple mixing system. The systems are completely miscible. There is no need to consider the appearance of the system microemulsion structure, and there is no need for the participation of other auxiliary agents or Razpršilci . Ima prednosti preprostega delovanja in visoke hitrosti ponavljanja in so lahko primerni za obsežno industrijsko proizvodnjo .
(5) Poly -olefin lubricant base oil (PAO) is an important type of synthetic hydrocarbon lubricating fluid. Compared with mineral lubricant base oil, PAO is obtained by chemical synthesis and has excellent low-temperature properties such as low pour point, high flash point, no sulfur in the oil, and less precipitation after oxidation. It has broad research prospects and development space among important synthetic hydrocarbon oils. Based on this, with the goal of synthesizing a "new generation of poly -olefin" lubricant base oil with excellent performance, the catalyst AlCl3 was used to catalyze the polymerization reaction of 1-dodecene and 1-tetradecene mixed olefins to obtain a mixture of poly -olefins (PAO) with different polymerization degrees. The mixture is a lubricant base oil component with a high viscosity index (158~170), medium viscosity (V100℃=18~29mm2/s), low pour point (PP=-16~-34℃), and zmerna molekulska teža (M =715 ~ 875) .
