Appl. No.:

12/468585

US Classification:

560222

Abstract:

A method and apparatus for preparing a N,N-dialkylaminoalkyl acrylate in a continuous transesterification reaction. The reaction involves adding alkyl acrylates such as methacrylate or ethacrylate to a reboiler mechanism and efficiently removing alcohol co-products. Because the reaction is continuous, the alkyl acrylates can be added as needed to increase output, decrease output, or fine-tune the reaction dynamics. An entrainer is used to form a volatile azeotrope which contains both alcohol and entrainer and which is easily removed from the reboiler mechanism. This method reduces the amount of entrainer needed per unit of alkyl acrylate used and eliminates any need to purify the end product from entrainer contamination of the resulting N,N-dialkylaminoalkyl acrylate product.

International Classification:

C07C 69/52

US Classification:

560222

Abstract:

The invention provides a method of continuously producing high quality quaternized N,N-dialkylaminoethyl (meth)acrylates (DMAEA. MCQ) that has a long shelf life and which is stable in water. The method involves placing starting materials into a continuously stirred tank reactor in the presence of less than 6% water. This low amount of water causes two liquid phases to form and prevents unwanted side reactions. The denser liquid phase contains DMAEA. MCQ and the lighter phase contains the starting materials. Liquid from the denser phase is removed from a position where little of the lighter phase has been mixed in. The removed liquid then has any last traces of the starting materials reacted into DMAEA. MCQ and strips away any starting materials with a gas flow. The resulting liquid is high purity DMAEA. MCQ.

Abstract:

A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more homo- or co-polymers of N-alkyl(alkyl)acrylamide synthesized by polymerizing one or more N-alkyl(alkyl)acrylamide monomers in a solvent comprising a glycol ether of formula CH—(CH)—(O—CH—CH)—OH where m is an integer of 0-1, and n is an integer ≧1.

Abstract:

Disclosed are the Rhodamine B esters of hydroxy C. sub. 2 -C. sub. 6 lower alkyl acrylates. Specifically, the hydroxy lower alkyl radical is a linear hydroxy lower alkyl radical having the hydroxy group attached to the terminal carbon atom. Also shown are copolymers of diallyldimetyl ammonium chloride which contains from 0. 01-2 mole percent of these Rhodamine B esters and their use in treating industrial waters.

Abstract:

The disclosure relates generally to reducing mercury emissions from a coal power plant. Specifically, a method for treating a gas stream containing mercury is provided that includes injecting a mercury oxidant or absorbent and a carrying agent into a gas stream that was produced by heating or burning a carbonaceous fuel comprising mercury. The carrying agent vaporizes after being injected into the gas stream. The mercury oxidant or absorbent and a carrying agent may be injected before passing the gas stream into a gas scrubber.
