Usage

General Description

OCTAETHYLENEGLYCOL OCTYL ETHER is a chemical compound that consists of a long hydrophobic tail attached to a hydrophilic head group. It is commonly used as a surfactant or emulsifier in various industrial and commercial applications. This chemical has the ability to reduce the surface tension of liquids and increase the stability of emulsions, making it suitable for use in products such as paints, coatings, adhesives, and personal care items. Additionally, OCTAETHYLENEGLYCOL OCTYL ETHER is often employed as a solubilizer in the formulation of pharmaceuticals and as a dispersing agent in agricultural chemicals.

Synthesis and properties of two surfactants containing polyoxypropylene block and short branched alkyl chain

Short branched alkyl polyoxypropylene sulfates, sodium isohexyl polyoxypropylene sulfate (i-HPS) and sodium isooctyl polyoxypropylene sulfate (i-OPS) were synthetized via propoxylation, sulfation, and neutralization three-step reactions, and characterized by FT-IR and 1H NMR. Their Krafft points were measured and the results were all below freezing point. Their critical micelle concentrations (cmc) and minimum surface tension (γcmc) determined by equilibrium surface tension were 54.74 mmol L-1 and 32.12 mN m- 1 for i-HPS, 15.57 mmol L-1 and 33.33 mN m-1 for i-OPS, respectively. The measurement of dynamic surface tension indicated that both the equilibrium values of surface tension and the time required for reaching the equilibrium decreased with the increasing concentration of surfactant solutions. The spreading ability on paraffin film researched through dynamic contact angle revealed that the droplet of i-HPS solution presented a minimum contact angle of 58.9°at a concentration of 150 mmol L-1, while the equilibrium contact angle of i-OPS droplet was 52.8°under the same condition. Their salt tolerance measurement showed that 1.0 wt% i-HPS solution and 1.0 wt% i-OPS solution could endure 183.1 g L-1, 143.9 g L-1 NaCl, 206.3 g L-1, 198.4 g L-1 MgCl2, and 229.7 g L- 1, 217.9 g L-1 CaCl2, respectively.

PRODUCTION OF HYDROXY ETHER HYDROCARBONS BY LIQUID PHASE HYDROGENOLYSIS OF CYCLIC ACETALS OR CYCLIC KETALS

A liquid phase hydrogenolysis of acetal compounds such as cyclic acetals and cyclic ketals are fed to a reaction zone and reacted in the presence of a noble metal catalyst supported on a carbon or silica support to make hydroxy ether mono-hydrocarbons in high selectivity, without the necessity to use acidic co-catalysts such as phosphorus containing acids or stabilizers such as hydroquinone.
