  Crystal Structure of 20-Methyl-Nonatriacontane ((C₁₉H₃₉)₂CHCH₃) and Its Compatibility with Nonatriacontane (C₃₉H₈₀)

  摘要：

  We synthesized a branched n-alkane sample M39 with a carbon number of the main chain n = 39 with the methyl group at the middle of the chain, and studied its crystalline structure and also compatibility with the corresponding linear homologue of C39. Results of SEM, DSC, X-ray diffraction, IR absorption, and Raman scattering measurements on solution-grown crystallized sample (SG-M39) and bulk-crystallized sample (BK-M39) reveal along with computer simulation that a triclinic type of crystal belonging to the space group P (1) over bar is predominantly realized in BK-M39, whereas an orthorhombic type of P2(1)2(1)2(1) is found to be coexistent for SG-M39 crystal. The phase diagram is constructed for the BK-M39/C39 binary system, which shows that the system does not form a solid solution and the respective molecules with a small amount of contaminant of another component develop their own crystal structures separately over the entire range of molar fraction of M39 from 0.05 to 0.95 studied.

  Metal salts of organic acids complexed with β-diketone compounds are multifunctional complexes useful in the formulation of stabilizers for halogenated resins. These complexes may be used jointly with other low toxicity intermediates, such as zinc or magnesium intermediates, to form effective stabilizers that are non-toxic and exhibit better performance than other known stabilizers, including those containing toxic heavy metals such as cadmium or lead. The complex is prepared utilizing a Claisen condensation reaction and precipitation with water and heptane.

  The present invention is directed to a process for synthesizing an internal ketone K1 by decarboxylative ketonization reaction of a fatty acid, a fatty acid derivative or a mixture thereof in a liquid phase with a metal compound as catalyst in a reaction medium, said process being characterized in that a ketone K2 at liquid state, which is identical or similar to the ketone K1, is introduced into the reaction medium. The so-synthesized internal ketone K1 can be used for the preparation of a variety of end compounds, including surfactants having a twin-tail structure or a Gemini structure.
