Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 2834-05-1, is researched, SMILESS is O=C(O)CCCCCCCCCCBr, Molecular C11H21BrO2Journal, Industrial & Engineering Chemistry Research called Crystallinity and Water Vapor Permeability of n-Alkane, Alcohol, Aldehyde, and Fatty Acid Constituents of Natural Waxes, Author is Leyva-Gutierrez, Francisco M. A.; Wang, Tong, the main research direction is crystallinity water vapor permeability alkane alc aldehyde fatty acid.Synthetic Route of C11H21BrO2.
Natural waxes are valuable industrial products consisting of complex chem. mixtures To probe the structure-function role of select constituents, model n-alkanes, alcs., aldehydes, and fatty acids of C18-19, C22-23, and C26-27 carbon chain lengths were synthesized and analyzed via calorimetry and X-ray powder diffraction. Pure compounds and binary mixtures crystallized into monoclinic (M), triclinic (T), and orthorhombic (O) lattices or combinations thereof. The C26 aldehyde formed an O lattice and exhibited one solid-solid phase transition similar to n-alkanes. The water vapor permeability (WVP) of model systems cast as films was determined For pure compounds, WVP decreased in the following order: fatty acid > even n-alkane > odd n-alkane > alc. > aldehyde. Increasing carbon chain length, which translates to increasing unit cell volume, decreased WVP. Binary mixtures generally exhibited a more complex relationship with WVP. These findings may be applicable to the agricultural postharvest, pharmaceutical, and paperboard coating industries.
