International Classification:

F17C 704

US Classification:

62 481

Abstract:

Provided is a novel system and method for delivery of gas from a liquefied state. The system includes (a) a delivery vessel holding a bulk quantity of liquefied gas therein; (b) a heat exchanger disposed on the delivery vessel to provide or remove energy from the liquefied gas only; and (c) a pressure controller for monitoring and adjusting the energy delivered to the vessel. The system and method allow for controlled delivery of liquefied gas from a delivery vessel at a predetermined flow rate. Particular applicability is found in the delivery of gases to semiconductor process tools.

Appl. No.:

8/606669

Inventors:

Kevin J. Theriot - Baton Rouge LA
Robert G. Irwin - Prairieville LA

International Classification:

C07C 208

US Classification:

585510

Abstract:

Alpha-olefin oligomers are produced by oligomerizing an alpha-olefin monomer with a catalyst system comprising boron trifluoride, a protic promoter, and a modifier which is (a) at least one 1,3-dioxolane, or (b) at least one 1,3-dioxane, or (c) a combination of (a) and (b). Use of these modifiers in the BF. sub. 3 -catalyzed oligomerization makes it possible to modify the promoted catalytic reaction so that product containing as much as 50% or more of dimer can be produced at high conversions, at modest reaction temperatures, and in short reaction periods.

Abstract:

Dialkyl malonate/alkyl acrylate Michael addition product mixtures having at least three acceptor moieties in a substantial number of the molecules can be consistently prepared without the need for long reaction times or the use of a large excess of the acceptor when the reaction is effected by gradually adding one molar proportion of a dialkyl malonate to at least three molar proportions of an alkyl acrylate which has been preheated to 60. degree. -80. degree. C. in admixture with an initiator and a phase transfer catalyst. In a preferred embodiment, the preheated mixture is maintained at 60. degree. -80. degree. C. for at least one hour before the dialkyl malonate is added in order to increase the percentage of product composed of the heavier components.

Assignee:

Amoco Corporation - Chicago IL

International Classification:

C07C 208

US Classification:

585525

Abstract:

Alpha-olefin oligomers are prepared by a process which comprises contacting an oligomerizable olefin monomer with a catalyst system comprising a catalytic amount of boron trifluoride, a protic promoter, and an organic modifier selected from the group consisting of phosphate, thiophosphate, phosphine oxide, and phosphine sulfide. The oligomerizable olefin monomer is a C. sub. 6 to C. sub. 20 linear olefin comprising at least 50 mole % alpha olefin.

Assignee:

BP Amoco Corporation - Chicago IL

International Classification:

C07C 204
C07C 202

US Classification:

585525

Abstract:

Alpha-olefin oligomers are produced by oligomering alpha-olefin monomer with a catalyst system comprising boron trifluoride, a protic promoter, and a special type of modifier. The modifier is a compound that satisfies the following criteria: (a) it has at least one moiety in which a carbonyl group is directly bonded to a nitrogen atom which is in turn bonded to two separate carbon atoms, (b) it is devoid of any nitrogen atom other than a nitrogen atom that is either (i) directly bonded to two separate carbon atoms and to a carbonyl group or (ii) is triply bonded to a single carbon atom, and (c) it is devoid of any protonic functional substituent. These modifiers control the oligomer product distribution and provide higher percentages of lower oligomers, especially dimers.

Amoco Corporation - Chicago IL

International Classification:

C07C 208

US Classification:

585525

Abstract:

Alpha-olefin oligomer is prepared by contacting an alpha-olefin monomer which contains from about 6 to about 20 carbon atoms with a catalyst system comprising boron trifluoride, a protic promoter, and an organic sulfone, sulfoxide, carbonate, thiocarbonate, or sulfonate. Oligomer containing as much as 50% or more of dimer can be produced at high conversions, at modest reaction temperatures, and in acceptably short reaction periods.

Abstract:

A leak detection system for flat commercial roof structures is disclosed in order to detect and subsequently repair a leak as soon as possible such that any damage to the roof, as well as to other structural and/or insulation components of the overall roof structure, can be minimized due to the absorption or migration of the water. The leak detection system may comprise elongated water detection sensor strips to be fixedly secured to at least two edge portions of insulation board assemblies, or alternatively, electrical circuits may be provided over the entire expanse of the major upper surface portion of each insulation board assembly, or alternatively still further, rolls of water detection sensor strips may be applied to different regions of the flat commercial roof structure.
