  • alkyl
  • The alkyl- and arylsulfonic acids have herbicidal properties, but they are not strong enough to be of practical importance. (springer.com)
  • Water soluble salts of poly(acrylic acid) and poly(methacrylic acid), copolymers of these acids with lower alkyl acrylates, natural gums such as alginates, proteins such as casein and cellulose derivatives such as hydroxyethyl cellulose are typically used throughout the industry as thickening aids. (google.de)
  • Preferred polymer latices contain about 75-95% by weight of the lower alkyl acrylate ester, about 1-7 by weight N-methylol acrylamide or N-methylol methacrylamide, 0.56% by Weight acrylic and/or methacrylic acid and less than 15% by weight of other polymerizable monomers. (google.de)
  • sodium
  • Because the sulfonic acids are frequently used in the form of their sodium salts, sulfonation is usually followed by neutralization with sodium hydroxide or sodium carbonate . (britannica.com)
  • Such operations are conducted on a manufacturing scale in the preparation of the sodium salts of TPPTS (used in catalysts as described above), in the preparation of alkylated benzenesulfonic acids (used as synthetic detergents), and in the preparation of anthraquinonesulfonic acid (used in the manufacture of alizarin and other dyes). (britannica.com)
  • Lysinibacillus sphaericus D3 cell-immobilized beads in natural gel sodium alginate decolorized the xylidine orange dye 1-(dimethylphenylazo)-2-naphthol-6-sulfonic acid sodium salt in the laboratory. (mdpi.com)
  • Sulfonate
  • A conventional oil-based drilling mud formulation is comprised of basically the following ingredients: oil (generally No. 2 diesel fuel), emulsifying agents (alkaline soaps and fatty acids), wetting agents (dodecylbenzene sulfonate), water, barite or barium sulfate, (weighting agent), asbestos (employed as viscosification agent) and/or, amine treated clays (also as viscosification agent).

  • composition
  • 1. A collagen composition comprising a polymerizable product formed by a reaction between (a) a partially fibrillar collagen derived by subjecting an acid solubilized collagen to a pH ranging from 7.0 to 7.6 and a temperature ranging from 25 C. to 37 C. for a time sufficient to initiate fibrillogenesis and (b) at least one of an acylating agent and sulfonating agent. (google.com.au)
  • 11. The collagen composition of claim 10 wherein the sulfonating agent is 2- (chlorosulfonyl)-anthraquinone or anthraquinone-1, 5-disulfonic acid. (google.com.au)
  • Chemistry
  • In spite of this limitation, Woroshzow's book is a mine of knowledge, not only for the dyestuff chemist, but also for all chemists who are interested in the principles of aromatic chemistry. (docme.ru)
  • dyes
  • Leather is dyed mainly by means of selected acid, substantive and metal-complex dyes and, to a minor extent, basic dyes. (google.com)
  • acrylate
  • The acrylic and methacrylic acid/acrylate ester copolymers are an important class of materials used to enhance latex viscosity, being ofiered in both latex and dry powder form, however, they are not without disadvantages. (google.de)
  • carbon
  • NH 2 CH 2 CH 2 SO 3 H), the sulfobacins and other sulfonolipids (the biologically active products from bacterial cultures that contain 15- to 17-carbon chains attached to the carbon and nitrogen of 2-aminoethanesulfonic acid), and the echinosulfonic acid C (an α-hydroxysulfonic acid containing two brominated indole rings). (britannica.com)
  • presence
  • Convenient and simple, sequential diazotization-iodination of aromatic amines with NaNO 2 /KI in the presence of a sulfonic acid based cation-exchange resin in water is an inexpensive, noncorrosive and eco-friendly synthetic route, that allows the preparation of various electron-rich and deficient iodoarenes in good yields. (organic-chemistry.org)
  • Products
  • Based on the results, the probable degradation products of xylidine orange were naphthol, naphthylamine-6-sulfonic acid, 2-6-dihydroxynaphthalene, and bis -dinaphthylether. (mdpi.com)
  • weight
  • The amount of the additive employed herein can vary, preferably, from 0.01 to about 10 weight percent based on the weight of the aromatic polycarbonate. (google.com)
  • particular
  • The particular additive employed herein is unique in that even very minor amounts render the aromatic polycarbonate flame retardant. (google.com)
  • means
  • One can point, for instance, to the discussion of the kinetics of alkali melts (p. 351) where it is shown that the experimental proof, usually attributed to J. F. Bunnett, for the two-stage mechanism of nucleophilic aromatic substitution by means of Bodenstein's equation for the stationary state, was given as early as 1938 by Woroshzow jun. (docme.ru)
  • minor
  • It has now been surprisingly discovered that an aromatic polycarbonate can be made flame retardant by incorporating with the aromatic polycarbonate minor amounts of certain additives, which additives are inert and do not degrade the aromatic polycarbonate. (google.com)
