标题:Stepwise Aggregation Of Dimethyl-Di-N-octylammonium Chloride In Aqueous Solutions: From Dimers To Vesicles
摘要:The Self-Aggregation Of Dimethyl-Di-N-octylammonium Chloride,In Diluted Aqueous Solutions,Was Studied With Various Experimental And Theoretical Techniques: Zetametry,Conductimetry,Dimethyl-Di-N-octylammonium And Chloride-Selective Electrodes,Tensiometry,NMR Spectroscopy (H-1 And Dosy),And Molecular Modeling (Pm3 And Molecular Dynamic). The Combination Of The Data Obtained By These Techniques Led Us To Propose It Stepwise Aggregation Process With Increasing Concentration: Dimers (0.2-10 Mm),Bilayers (10-30 Nm) And Finally Vesicles (> 30 Nm).

摘要:A process for the production of a phthalocyanine pigment having a clear color tone, a high tinting strength and a finely milled structure by an efficient and economical process, in which the pigmentation from a phthalocyanine crude can be carried out without removing an aromatic hydrocarbon solvent used in the synthesis of the phthalocyanine crude, the process comprising thes steps of n (a) reacting phthalic anhydride or its derivative, urea or its derivative and a catalyst in an organic solvent to synthesize a phthalocyanine crude, n (b) wet-milling a slurry of the synthesized phthalocyanine crude in the presence of a milling medium without removing the aromatic hydrocarbon solvent, and n (c) removing the organic solvent from the slurry of the milled product, purifying the milled product and drying the milled product with a spray type dryer.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.

摘要:A composition and method for inducing and inflicting damage to cell membranes of microorganism by inducing changes in membrane permeability caused by polycation-induced membrane pores. The control of Clostridium difficile spores with an efficacy of 99.99% on hard surfaces is provided. The invention includes the application of an evaporation-induced self-assembly, surfactant-mediated synthesis or self-condensing polymer, which forms a film which is both flexible on the surface as a nano-polymeric coating and with refractive index yielding a transparent coating. The polymeric matrix includes various biocidal polymeric cationic quaternary salts, one being a silyl quaternary having a kinetic zeta potential to disrupt bacterial spores functions. The polymeric matrix consist of multiple small molecule biocides as well as polymerics biocide combinations not otherwise seen to develop an surface topography of peaks and troughs in the nano range to resist bacterial adhesion factors and subsequent biofilm formation. The surfactants induce self-assembly film topography.
