The present invention relates generally to methods for producing detergent compounds from waste plastic feedstocks. More specifically, the invention relates to methods for producing detergent intermediates, including alkylbenzenes, paraffins, olefins, oxo alcohols, and surfactant derivatives thereof from waste plastic feedstock.

In a process for the epoxidation of an olefin with hydrogen peroxide in the presence of a solvent, where a mixture comprising olefin, an aqueous hydrogen peroxide solution and a solvent is continuously passed through a fixed bed of an epoxidation catalyst comprising a titanium zeolite, addition of a chelating agent to the aqueous hydrogen peroxide solution before mixing it with solvent reduces or prevents formation of deposits on the catalyst and blocking of orifices of a liquid distributor.

Provided herein are cyclodecynes, including chiral cyclodecynes, and methods of making cyclodecynes. The methods may include providing a 1,1-biaryl compound substituted independently at the 2-position and the 2-position with a hydroxyl or an amino group; and contacting the 1,1-biaryl compound with a protected but-2-yne-1,4-diol to form the cyclodecyne.

Disclosed in the present invention is a method for preparing 2-iodo aryl ether under the action of alkali metal hydride: adding alkali metal hydride and phenol to a solvent, then adding 1,2-diiodoarene, and reacting at 0-100? C. to obtain a 2-iodo aryl ether product. The coupling process of the present invention does not require the addition of a transition metal catalyst, and does not cause metal contamination to the product; the method of the present invention can be performed at room temperature and has high functional group compatibility, and solves the problem that existing metal-catalysed coupling to aryl ether reactions need to be performed at a relatively high temperature.

Described herein are improved chemical reactors for carrying out partial oxidation reactions. The chemical reactor permits the use of levels of oxygen above the lower explosion limit (LEL) typically used in partial oxidation reactions, which increases both volumetric reactivity and conversion per pass, resulting in reduced separation and reactant recycle costs. Also described are methods of using the reactors.

Benzotriazole phenols with substituents either ortho to the phenol hydroxyl group and/or para to the phenol hydroxyl group can be prepared from the unsubstituted benzotriazole phenol by coupling reactions. The ortho substituent group can be a simple alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenol to another benzotriazole phenol group.
