20160090609 | ADDITIVE FOR BIOETHANOL FERMENTATION PROCESS AND METHOD FOR PRODUCING BIOETHANOL - An object of the present invention is to provide an additive that can improve the production efficiency. The present invention is an additive for a bioethanol fermentation process comprising a polyoxyalkylene compound (A) having a Griffin's HLB value in the range of 0 to 6 and a polyoxyalkylene polyol (B). The compound (A) is preferably a mixture of a compound represented by a general formula (1) and a compound represented by a general formula (2). R1O-(AO)m-R2 (1). R3O-(AO)n-(EO)p-R4 (2). R1 and R3 represent alkyl or alkenyl, R2 and R4 represent a hydrogen atom or a monovalent organic group, AO represents oxyalkylene having a carbon number of 3 to 18, or a reaction residue of glycidol, an alkyl glycidyl ether or alkenyl glycidyl ether, EO represents oxyethylene, m and n are 1 to 100, and p is 3 to 10. | 03-31-2016 |
20140221508 | DEFOAMING AGENT - An object of the present invention is to provide an oil-in-water emulsion defoaming agent that is superior in defoaming properties (initial defoaming property and defoaming durability) and stability (emulsion stability). The present invention provides an oil-in-water emulsion defoaming agent including hydrophilic fumed silica (C), wherein an oil phase (A) is emulsified and dispersed in a water phase (B). Preferably, the content of the oil phase (A) is 10 to 50% by weight, the content of the hydrophilic fumed silica (C) is 0.1 to 6% by weight, and the content of the water phase (B) is 44 to 89.9% by weight based on the weight of the oil phase (A), the hydrophilic fumed silica (C), and the water phase (B). The weight ratio (A/C) of the oil phase (A) to the hydrophilic fumed silica (C) is preferably from 2 to 100. | 08-07-2014 |
20140100293 | DEFOAMING AGENT - The present invention provides a defoaming agent containing, as essential components, hydrophobic dry silica (S) prepared by hydrophobizing silica prepared using a dry process and having a primary particle diameter of 5 to 100 nm, water, and a hydrophobic liquid (Q) containing 1 to 25% by weight of an ester compound (E) represented by the following formula, (R | 04-10-2014 |
20110281985 | DEFOAMING AGENT - The object of the present invention is to provide a defoaming agent that is superior in defoaming properties (foam-breaking, foam-inhibiting effect, defoaming durability). | 11-17-2011 |
