Paragraph 0059-0062; 0068, (2017/06/02)
The present invention relates to a process and an apparatus for producing a carboxylic acid amide compound, and more particularly, to a process for producing a carboxylic acid amide compound which alternately performs a reaction process of a first manufacturing process that promotes the reaction between a first carboxylic acid and a first ammonia in the presence of a first catalyst and a reaction process of a second manufacturing process that promotes the reaction between a second carboxylic acid and a first ammonia in the presence of a second catalyst wherein each of them is progressed alternately between each preparation process so that the reaction between the carboxylic acid and the ammonia, which is intermittently carried out by the respective preparation processes, can be continuously performed, and moreover, the time required for the respective preparation processes is shortened, so that the carboxylic acid amide compound can be produced in a large amount in a short time.

Primary fatty acid amides are a group of bioactive lipids that have been linked with a variety of biological processes such as sleep regulation and modulation of monoaminergic systems. As novel forms of these molecules continue to be discovered, more emphasis will be placed on selective, trace detection. Currently, there is no published experimental determination of collision induced dissociation of PFAMs. A select group of PFAM standards, 12 to 22 length carbon chains, were directly infused into an electrospray ionization source Quadrupole Time of Flight Mass Spectrometer. All standards were monitored in positive mode using the [M + H]+ peak. Mass Hunter Qualitative Analysis software was used to calculate empirical formulas of the product ions. All PFAMs showed losses of 14 m/z indicative of an acyl chain, while the monounsaturated group displayed neutral losses corresponding to H2O and NH3. The resulting spectra were used to propose fragmentation mechanisms. Isotopically labeled PFAMs were used to validate the proposed mechanisms. Patterns of saturated versus unsaturated standards were distinctive, allowing for simple differentiation. This determination will allow for fast, qualitative identification of PFAMs. Additionally, it will provide a method development tool for selection of unique product ions when analyzed in multiple reaction monitoring mode.

In lizards, the epidermal glands of the femoral and precloacal regions are involved in the production of semiochemicals. In addition to its femoral glands, the giant girdled lizard, or sungazer, Cordylus giganteus, which is endemic to South Africa, has generation glands as an additional potential source of semiochemicals. These epidermal glands are described as glandular scales that overlay the femoral glands and are included in the normal epidermal profile located in the femoral (thigh) and anterior antebrachial (fore-leg) regions of the male sungazer. GC-MS analysis of the generation gland secretions and the trimethylsilyl derivatives of some of the steroidal constituents was employed to identify 59 constituents, including alkenes, carboxylic acids, alcohols, ketones, aldehydes, esters, amides, nitriles, and steroids. The quantitative differences of the volatile constituents of the fore- and hind-leg generation glands were compared between individuals. This is the first report on the chemical composition of generation glandular material of lizards.
Effect of cosolvent on the lateral order of spontaneously formed amphiphilic amide two-dimensional crystallites at the air-solution interface

At low temperature (5-12 °C), uncompressed films of insoluble amphiphilic molecules C19H39X, where the head group X contains one (CONH2, 1) or two (CONHC2H4CONH2, 2) amide groups, spontaneously form two-dimensional (2D) crystalline clusters over aqueous subphases containing soluble amide or carboxylic acid molecules. These crystallites were detected and their structures were studied using grazing incidence X-ray diffraction (GID). In the presence of subphases containing carboxylic acid (RCO2H, R = H, CH2Cl) at sufficiently high concentrations, a loss of diffraction signal was observed for 1, while amide and less concentrated acid subphases did not show such a destructive effect. The effect of the subphase solute molecules was understood in terms of the different ways in which the solutes hydrogen bond to the amide head groups of the amphiphiles. Both amide and acid solute molecules can form hydrogen-bonded cyclic dimers with the amide head groups. With an amide subphase, such dimers lead to an extension of the hydrogen-bonding network of the crystallites, and thus enhance its stability, but acid molecules may also bind to the monolayer at low concentrations with less than full occupancy. At high acid concentration, and thus more extensive formation of cyclic dimers between carboxylic acid and amphiphilic amide molecules, repulsive interactions between lone pair electrons on oxygen atoms of bound acid molecules inhibit formation of ordered arrays of these dimers and lead to a lack of diffraction signal. In 2, the second amide group strengthens the crystallites to the extent that there is no decrease in crystallinity over a 1 M formic acid subphase. The shape of the intensity profiles of the Bragg rods and the specular X-ray reflectivity measurements of 2 indicate formation of molecular trilayers.
Mixed Monolayers for the Design of Structured Surfaces To Induce Oriented 3-D Crystallization

Mixed monolayers containing two different amphiphiles C19H39CONHCH2CH2CO2H(A) and C19H39CONH2(B) were designed in order to form a two-dimensional (2-D) crystalline solid solution in which the A-type molecules form domains within the sea of B-type molecules.A "continuous" 2-D arrangement of the aliphatic chains was expected, driven by the amide hydrogen bonding requirement; a tendency for the formation of the embeded A-type domains should be provided by the interactions between the -CH2CH2CO2H head group moieties.The mixed monolayers served to promote the oriented nucleation of silver propionate 3-D crystals attached at the monolayer-solution interface.Only the A-type domains induced silver propionate crystallization whereas the B-type domains were essentially inert.The mixed A + B monolayers were found to be efficient nucleators down to a 1:10 molar ratio, providing proof for the existence of A-type domains.Additional information such as the structure and ion-binding properties of the mixed monolayers was furnished by specular X-ray reflectivity and grazing incidence X-ray diffraction using synchrotron radiation.
