  • Process for preparing sulfates and/or sulfonates in a micro-reaction system
    Patent number: 8921588
    Abstract: Suggested is a process for preparing sulfates and/or sulfonates by adding sulfur trioxide to a compound comprising at least one hydroxyl function and/or at least one double bond, which is characterized in that (i) the reaction is performed in a micro-reaction system (?-reactor), (ii) the sulfation/sulfonation agent used is a liquid sulfur trioxide, and (iii) the reaction is conducted in the presence of 0 to 20 Vol.-% of air, inert gas or organic solvents.
    Type: Grant

  • Process For Preparing Sulfates And/Or Sulfonates In A Micro-Reaction System
    Publication number: 20140303393
    Abstract: Suggested is a process for preparing sulfates and/or sulfonates by adding sulfur trioxide to a compound comprising at least one hydroxyl function and/or at least one double bond, which is characterized in that (i) the reaction is performed in a micro-reaction system (pt-reactor), (ii) the sulfation/sulfonation agent used is a liquid sulfur trioxide, and (iii) the reaction is conducted in the presence of 0 to 20 Vol.-% of air, inert gas or organic solvents.

  • Aqueous suspensions of low solubility and low stability water additives
    Patent number: 6281169
    Abstract: A method of improving the rate of dissolution in water of low solubility compounds by combining a low solubility compound with a rheology additive that is made of platelets or particles which orient together with ionic or hydrogen bonds. The inventive method also may improve the hydrolytic stability of hydraulically unstable low solubility compounds.
