Alkyl naphthalene sulfonates

There are three main uses for naphthalene sulfonic acid derivatives (75—79) as naphthalenic tanning material alkyl naphthalene sulfonates for industrial appHcations as nondetergent wetting agents and as dye intermediates. Consumption of naphthalene sulfonates as surfactants accounts for a large portion of usage. Naphthalene sulfonate—formaldehyde condensates are also used as concrete additives to enhance flow properties. Demand for naphthalene sulfonates in surfactants and dispersent appHcations, particularly in concrete, was expected to increase into the twenty-first century. Consumption as of 1995 was 16 x 10 kg/yr. [Pg.79]

Quaternary ammonium salts and salts of alkyl naphthalene sulfonic acid were some of the first compounds to be used effectively as fuel demulsifiers and dehazers. Today, a wide range of monomeric and polymeric demulsifiers and dehazers exist. [Pg.146]

Explosive Mixtures of High Density. A method of prepn, patented by Cook 8i Davis, involves subjecting two solid chem compds, at least one of which is a nitrated org compd (such as a mixt of TNT, An and (other compds), to a temperature at which at least a portion of one of the compds is in molten condition. To this molten mass is added a dispersing agent (such as a Na alkyl naphthalene sulfonate or other suitable org sulfonate or fatty acid soap) and then, after thorough blending, the mass is cooled and solidified. Several examples with details are given... [Pg.295]

This material is a sodium salt of an alkyl naphthalene sulfonate, and is, therefore, anionic in nature, exhibiting excellent efficiency and compatibility under alkaline conditions. This material is frequently used in vat dyeings where alkaline compatibility is a requirement. [Pg.293]

The polysulfide polymers are prepared as a suspension by condensation of the dihalide monomer with polysulfide in aqueous solution [18]. Bis-2-dichloro-ethyl formal is the monomer usually used, and 0.1-0.4% 1,2,3-trichloropropane is added as a crosslinking monomer [19]. In conducting polymerization, the standard practice is to feed the dihalide monomer into the aqueous polysulfide solution containing specific suspending and nucleating agents. A combination of an alkyl naphthalene sulfonate with magnesium hydroxide sol prepared in situ is commonly used. [Pg.459]

Flash rusting is the phenomenon of formation of small brown rust spots that appear very soon after application of waterbased systems directly to steel. The problem is more prominent when the steel surface is active (for example, after blasting) and the pH is <7. To combat this problem, flash-rust inhibitors are added to waterbased coatings. They should have good water solubility. Flat surfaces are relatively easy to protect, while weld areas are considered difficult. Flash-rust inhibition at a weld area can be achieved by a combination of different products. Flash-rust inhibitors are typically based on ammonium and sodium nitrites, benzoates, metaborates and phosphates, occasionally in combination with materials such as morpholine and amino methyl propanol. Some other organic salts are also used, such as amine salts of 2-mercaptobenzothiazolyl succinic acid and calcium or barium salts of linear alkyl naphthalene sulfonic acids. Typically they are used at levels of 0.1 to 1.0 % of the total mass of paint. They also help in preventing in-can corrosion upon storage of aqueous paint. [Pg.275]
