The present invention provides strategies to improve the moisture management properties of textiles while retaining high comfort levels. The treatments also help to protect textiles against microbial growth. The treatment strategies of the present invention are based at least in part on the use of cationic bis-imidazoline(s) and their salts. Quaternized bis-imidazoline cations and their salts are particularly preferred.

Textile treatment compositions including quternary bis-imidazoline compounds derived from linear tetramines useful to improve moisture management and provide antimicrobial protection

The present invention provides corrosion inhibiting compositions that incorporate at least one bis-imidazoline compound. In the practice of the present invention, a tetramine admixture enriched with respect to linear tetramine is used to prepare the bis-imidazoline compound. 'Enriched' means at least 70 weight percent and up to 100% of the tetramine species included in the admixture includes a linear tetramine such as L-TETA.

The hydration of clays and shale in drilling operations may be inhibited by employing an aqueous based drilling fluid comprising a shale hydration inhibition agent comprising a polyaminopolyamide-epichlorohydrin resin, preferably the polyamino polyamide-epichlorohydrin resin is a reaction product of an aliphatic polyamine, an aliphatic polycarboxylic acid, and epichlorohydrin. The shale hydration inhibition agent should be present in the aqueous based drilling fluid in sufficient concentration to reduce the reactivity, such as swelling, of clays and shale when exposed to water-based drilling fluids.

The present disclosure is directed to a single phase acetylated castor component (SP-ACC). An acetylated castor component is purified to produce the SP-ACC which contains a reduced amount of, or no, insoluble component(s) therein. The SP-ACC enhances the performance and properties of plasticizers of which it is a component.

Use of a specific combination of catalysts for the first and second steps of the process for the conversion of CHP to BPA provides high yields of BPA and low impurity yields, without a requirement for the intermediate purification steps. In the first step, CHP is cleaved in the presence of an acid treated clay such as acid treated Montmorillonite clay to produce phenol and acetone. In the second step, the phenol and acetone produced is reacted, preferably without intermediate purification, in the presence of a cation exchange resin catalyst that includes a cation exchange resin and a mercaptan or mercaptoalkanoic acid promoter to produce BPA.

Use of a specific combination of catalysts for the first and second steps of the process for the conversion of CHP to BPA provides high yields of BPA and low impurity yields, without a requirement for the intermediate purification steps. In the first step, CHP is cleaved in the presence of a sulfated metal oxide catalyst such as sulfated Zirconia to produce phenol and acetone. In the second step, the phenol and acetone produced is reacted, preferably without intermediate purification, in the presence of a cation exchange resin catalyst that includes a cation exchange resin and a mercaptan or mercaptoalkanoic acid promoter to produce BPA.

A process for producing a phenol product generally comprises a first step comprising reacting in a first reactor a feed stream comprising cumene hydroperoxide and water with an acid catalyst to produce an effluent comprising the phenol product, acetone, and at least 1% by weight residual cumene hydroperoxide, and a second step comprising passing the effluent into a second reactor and decomposing the residual cumene hydroperoxide, wherein during said process the ratio of phenol to acetone is maintained at a molar ratio of greater than 1:1, and wherein the water in each of the first and second steps is present in an amount more than 0 and less than or equal to 5 weight percent based on the total weight of the feed stream or effluent, and wherein the process is continuous.

Process for producing phenol

A process for converting carbonyl-type impurities contained in a phenolic solvent to high-boiling derivatives is provided by contacting the phenolic solvent with a hydrotalcite-type material (HTM). The phenol can be separated from the high-boiling derivatives using conventional separation techniques, such as distillation, so the invention also provides a process for separating carbonyl-type impurities, such as hydroxyacetone (HA), from a phenolic solvent. The process can be applied in the conventional industrial process for converting cumene to phenol to remove carbonyl-type impurities from the phenol product. A process and a facility for producing purified phenol by converting cumene to phenol are provided. In the conversion of cumene to phenol, the phenol often contains carbonyl-type impurities. The phenol and carbonyl-type impurities are reacted in the presence of an HTM to produce phenol and high-boiling derivatives. The phenol may be further purified using conventional separation techniques, such as distillation, to remove the high-boiling derivatives.
