TL;DR: In this paper, the authors described a process for alkylating aromatics comprising the steps of: (1) contacting a mixture of hydrogen and carbon monoxide with a Fischer-Tropsch catalyst at conditions effective to form a first gas mixture containing an alkylated agent selected from ethylene or mixtures of ethylene and propylene; (2) removing from the first mixture components capable of alkylation and having boiling points higher than the selected alkylate agent, and (3) combining the second gas mixture with sufficient alkylatable aromatic hydrocarbon to form
Abstract: The disclosure describes a process for alkylating aromatics comprising the steps of: (1) contacting a mixture of hydrogen and carbon monoxide with a Fischer-Tropsch catalyst at conditions effective to form a first gas mixture containing an alkylating agent selected from ethylene or mixtures of ethylene and propylene; (2) removing from the first gas mixture components capable of alkylating aromatics and having boiling points higher than the selected alkylating agent to form a second gas mixture which contains less than about 10 mole percent of the selected alkylating agent and more than about 5 mole percent each of carbon monoxide and hydrogen; (3) combining the second gas mixture with sufficient alkylatable aromatic hydrocarbon to form a third mixture containing at least about a 1 to 1 aromatic to alkylating agent mole ratio; and (4) contacting the third mixture with a heterogeneous alkylation catalyst at conditions effective to alkylate the aromatic hydrocarbon.

TL;DR: In this article, the swelling properties of some engineering polymer membranes in the presence of monocyclic aromatic hydrocarbons have been studied from the solvent immersion experiments and diffusion coefficients have been extracted from the swelling results.
Abstract: Swelling properties of some engineering polymer membranes in the presence of monocyclic aromatic hydrocarbons have been studied from the solvent immersion experiments. The liquids were chosen with varying methyl and methoxy substitutions to study the effect of substitutions on their transport properties. Diffusion coefficients have been extracted from the swelling results. The concentration dependence of diffusion coefficients has been investigated

TL;DR: In this paper, solid polyurethane resins containing a non-compatible hydrocarbon oil homogeneously dispersed therein are prepared by thoroughly admixing the reactants, a low aromatic hydrocar oil, and particular emulsifying and thixotropic colloidal agents.
