SINGLE COMPOSITION COMPRISING A DISINFECTANT AND A LUBRICANT COMBINED WITH A METHOD OF USING SAID COMPOSITION COMPRISING TO DISINFECT AND/OR LUBRICATE A FLUID ENCOMPASSING SYSTEM
A combination of a method using a composition utilized together to disinfect and/or lubricate a fluid encompassing system. A single composition comprising a disinfectant and a lubricant comprises water-alcohol-glycerin-chlorhexidine gluconate.
This composition is used together with a method of purging this fluid encompassing system, adding said composition into said system, and flushing/rinsing said system. This method ensures that this composition is not diluted and that this composition directly contacts the microbial contamination and biofilm in this system.
This method using this composition maintains and controls this system's encompassing fluid chemical and physical properties by disinfecting and/or lubricating said fluid encompassing system and said system's fluid system components comprising of fluid conduit(s), and/or fluid reservoir(s), and/or valve(s), and/or device(s) that connect to this system's fluid system.

One vessel process for making 1,2-propanediol from a high fructose feedstock
A process is described for directly converting a high fructose feedstock to a product mixture including one or more lower polyols in which 1,2-propanediol is produced in preference to any other lower polyols, wherein a high fructose feed and a source of hydrogen are supplied to a reaction vessel and reacted in the presence of a copper-containing, supported ruthenium catalyst to provide the product mixture.

Processes for obtaining a polyol from palm oil, polyols obtained from the processes, products derived from such polyol and their method of preparation
The present invention relates to the process for production of a polyol from palm oil and of rigid polyurethane foams prepared from said polyol derived from palm oil. On the one hand, this invention provides a method for obtaining monomeric polyols from palm oil that have hydroxyl number between 50 450 mgKOH/g sample. The polyols of the present application may be obtained by means of a procedure based on the following four mother routes: Route 1: maleinisation of the fatty acids of palm oil; Route 2: glycerolysis of palm oil; Route 3: trancesterification of palm oil; and Route 4: epoxidation of unsaturated carbon-carbon links of palm oil. Additionally, other modalities of the invention permit obtaining polyols from the combination of these mother routes. In other realizations of the invention polyurethanes are prepared from polyols obtained through any of the four routes or by combinations of the same.
