    Abstract: Processes for producing propylene glycol monoalkyl ether are described herein and include contacting propylene oxide and an alcohol in the presence of an alkali or alkaline earth metal alkoxide catalyst to produce an alkoxylation mixture including propylene glycol monoalkyl ether; distilling the alkoxylation mixture to produce a first overhead stream including propylene oxide and the alcohol and a first bottoms stream including propylene glycol monoalkyl ether; distilling the first bottoms stream to produce a second overhead stream including purified propylene glycol monoalkyl ether and a second bottoms stream including heavier byproducts; further distilling the second bottoms stream to form a resulting bottoms stream including caustic and heavier byproducts; introducing an alkali metal borohydride into at least a portion of the resulting bottoms stream to form an alkali metal borohydride containing stream; and introducing the alkali metal borohydride containing stream into one or more distillations upstream of recovery of the second overhead stream.

    Abstract: This is to provide a process for producing an alkylene oxide adduct which can continuously produce the alkylene oxide adduct with an optional size from a small size to a large size, a temperature and a pressure at the time of the addition reaction can be controlled with high precision, and as a result, the alkylene oxide adduct with high quality having no coloring and narrow molecular weight distribution can be continuously produced, and the above can be accomplished simultaneously, and such an alkylene oxide adduct.An alkylene oxide adduct was produced by using a microflow reactor having a flow passage with an inner diameter of 0.05 to 3.5 mm, continuously supplying a predetermined amount of alkylene oxide and a predetermined amount of an organic compound having an active hydrogen atom(s) to the flow passage in a liquid state, and these materials were reacted while passing therethrough under the conditions of a temperature of the flow passage of 70 to 200° C. and a pressure of the supply port of the flow passage of 1 to 10 MPa.

    Abstract: Crude bisphenol A containing a ketone solvent remaining form its manufacture and having a melting point of 150° C. or higher may be reacted with one or more alkylene oxide, in the absence of any added ketone solvent, at reduced temperatures compared with conventional, molten methods to give a fully alkoxylated adduct product having reduced color. By at least partially alkoxylating the bisphenol A, its potential for crystallization is disrupted and the partially alkoxylated bisphenol A has a lower melting point than the original bisphenol A permitting it to be more readily further alkoxylated at the reaction temperature. The alkoxylation reaction may be conducted at a temperature in the range of about 30 to about 140° C. Suitable catalysts may include tertiary amines or caustic compounds such as NaOH and KOH.

    Abstract: A process for mineral oil production, in which an aqueous formulation comprising tris(2-hydroxyphenyl)methane of the general formula (I) is injected into a mineral oil deposit through an injection well and the crude oil is withdrawn from the deposit through a production well, where the R1, R2 and R radicals in the formula (I) are each defined as follows: R is independently 1 to 2 hydrocarbyl radicals per phenyl ring, R1 is preferably H or OH, R2 are independently radicals of the general formula (III), —(R5—O—)n—R6—X  (III) where n is a number from 1-50, and where the R5 radicals are R7 groups R6 is a single bond or an alkylene group having 1 to 10 carbon atoms, X is H or an acidic end group, R10 is, for example, C1-C6-hydrocarbyl radical, enables improved mineral oil production.
