Embodiment 1

[0228] Reality Example 1: Synthesis of ethoxylated 2,3-butanediol

[0229] reaction :

[0230] 2,3-Butanediol (2,3-BDO) was added to the reactor along with catalyst (0.5 mol% potassium as 25% potassium methoxide in methanol solution). The reactor was purged to remove air using vacuum and nitrogen circulation. Volatile materials (methanol and water) were removed by nitrogen sparging at 110°C-115°C and vacuum (bubbling was done with a slow nitrogen trickle through the bottom drain valve while using water pump vacuum). After 1-2 hours, the reactor was filled with nitrogen and vented to 0-5 psig, then heated to between 110°C and 125°C. Add ethylene oxide slowly while stirring at 400 rpm (used throughout) and maintain pressure below 200 psig. Each step of the reaction was allowed to run until the pressure decreased, leveled off, and was constant for at least 30 minutes.

[0231] Continue to add ethylene oxide until the desired degree of ethoxylation is achieved, as measured...

Abstract

The present invention relates generally to surfactant and detergent compositions and, more specifically, to surfactant and detergent compositions containing an ethoxylated diol.

Description

technical field [0001] The present invention relates generally to surfactants and detergent compositions, and more particularly to surfactants and detergent compositions containing ethoxylated glycols. Background technique [0002] Many consumers prefer fluid detergent products, such as liquids, gels, pastes, etc., over solid detergents. In addition to water, fluid detergent products may also contain surfactants, such as anionic surfactants, and one or more solvents. Solvents can provide multiple benefits: solvents can allow formulation of anionic surfactant-rich surfactant systems especially for compact fluid detergents; solvents can adjust the viscosity of formulations; solvents can allow formulation of isotropic and physically stable formulations and solvents may allow formulation of enzymes, polymers, bleaches, chelating agents, and other ingredients that improve cleaning. The solvent can also be used to formulate a stable shippable anionic surfactant concentrate which...
