The present disclosure provides for a composition and method for attracting bed bugs to a trap or to a location where an insecticide or pesticide is present, or to a trap or a location where a bed bug infestation can be detected. The present disclosure provides for a composition for attracting bed bugs that includes one or more of methyl diethanolamine (MDEA), monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA), and dimethyl trisulfide (DMTS); a carrier; and optionally one or more amides selected from oleamide, octanamide, nonanamide, and laurylamide; urea, biuret, or triuret; and one or more aliphatic fatty acids. The present disclosure further provides for a method for treating an article by applying the composition to the article, where the article comprises a device for trapping or detecting bed bugs or a device for treating a bed bug infestation.

Composition for detection and treatment of bed bugs

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&#x2014;(CH)&#x2014;(O&#x2014;CH&#x2014;CH)&#x2014;OH where m is an integer of 0-1, and n is an integer &#x2265;1.

Method of controlling gas hydrates in fluid systems

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. Water can then safely be added to ease in the transport and use of the produced DMAEA.MCQ.

Continuous production of DMAEA quaternary salts

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.
