8956 results about "Sulfonic acid" patented technology

A sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O)₂−OH, where R is an organic alkyl or aryl group and the S(=O)₂(OH) group a sulfonyl hydroxide. As a substituent, it is known as a sulfo group. A sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. The parent compound (with the organic substituent replaced by hydrogen) is the parent sulfonic acid, HS(=O)₂(OH), a tautomer of sulfurous acid, S(=O)(OH)₂. Salts or esters of sulfonic acids are called sulfonates.

Biocidal applications of concentrated aqueous bromine chloride solutions

InactiveUS6322822B1Difficult to killEfficient solutionBiocideStampsChloride saltBromine
Methods for disinfecting surfaces and for sanitizing bodies of water using a single-feed, bromine-based biocide are described. These methods use concentrated liquid biocide compositions comprising biocidally active bromine as the biocide. Also described is a process of producing the concentrated liquid biocide composition: mixed together are (a) bromine chloride and (b) an aqueous solution of alkali metal salt of sulfamic acid having a pH of at least about 7, in amounts such that (i) the active bromine content of the composition is at least about 100,000 ppm (wt / wt), and (ii) the atom ratio of nitrogen to active bromine in the composition is greater than 0.93. Use of bromine chloride as the source of the active bromine in the process is advantageous because in the resulting aqueous compositions, all of the bromine of the bromine chloride is made available as active bromine in solution. In other words, the chlorine of the bromine chloride is converted in the process to dissolved alkali metal chloride salt, thereby liberating all of the bromine as the active bromine content of the biocidal composition.

Microemulsion heavy wax crystal emulsifying dispersant applied to oil well for tertiary oil recovery

The invention relates to a microemulsion heavy wax crystal emulsifying dispersant applied to an oil well for tertiary oil recovery, and is mainly used for solving the problem that the oil production rate is influenced due to the high return pressure and the short thermal washing period of the oil recovery well caused by that serious wax precipitations are generated by the oil well which contains thickened oil and is high in polymer flooding and viscosity. The emulsifying dispersant is prepared from the following components by weight percent: 1% to 3% of high-molecular polymer wax inhibitor, 13% to 25% of organic aromatic solvent, 1% to 3.5% of emulsifying agent, 8% to 12% of sulfonate, 10% to 12.5% of alcohol, 10% to 20% of demulsifier and 25% to 35% of water.
