The present disclosure provides a process. In an embodiment, the process includes providing a first blend composed of nonanals, Colefins and C-Calkanes. The process includes adding, to the first blend, a component selected from Caldehyde, Caldehyde, and combinations thereof to form a non-aqueous reaction mixture having an initial water content from 0 wt % to 10 wt % water. The process includes introducing an organic base catalyst to the non-aqueous reaction mixture and heating the non-aqueous reaction mixture to a temperature from 30° C. to 100° C. and cross-aldol condensing the non-aqueous reaction mixture. The process includes forming a cross-aldol product composed of a component selected from Cenals, Cenals, Cenals, Cenals, and Cenals, and combinations thereof.

Embodiments of the present disclosure are directed towards methods of etherification including modifying a zeolite catalyst with silica to provide a silica modified zeolite catalyst; and contacting the silica modified zeolite catalyst with an olefin and an alcohol to produce a monoalkyl ether.

Methods of etherification

A method including the step contacting an olefin, an alcohol, a metallosilicate catalyst and a solvent, wherein the solvent comprises structure (I): wherein Rand Rare each selected from the group consisting of an aryl group and an alkyl group with the proviso that at least one of Rand Ris an aryl group, further wherein n is 1-3.

A mixture of octanols, nonanols and decanols is useful for the preparation of alkoxylates, which alkoxylates may be used as surfactants, which surfactants have surprisingly good biodegradability.

Readily biodegradable alkoxylate mixtures

Treat an aggregation of particulates with two different aqueous mixtures, first with an aqueous mixture containing a sulfonated aromatic polymer component and then with an aqueous mixture containing polyethylene oxide.

The disclosure provides compositions and methods for inhibiting corrosion of a copper surface using a bis-imidazoline compound having an aromatic group, such as an aryl bis-imidazoline. The bis-imidazoline corrosion inhibitor can provide one or more advantage in use such as synergistic performance in aqueous and acidic media at low active dosages, resistance to decomposition or degradation in the presence of harsh reagents, ease of dispersion in an aqueous system, and improved thermal stability over conventional triazole based inhibitors. The disclosure also provides methods for the synthesis of bis-imidazoline compounds.
