摘要:
The invention relates to a method for producing linear butenes from methanol. The problem addressed is that of specifying such a method in which the methanol used is converted, to the largest possible extent, into butenes. The problem is solved by combining a methanol-to-propylene process with a metathesis reaction by means of which the propene obtained from the methanol is converted into linear butenes.

Solid-fueled torches, wherein the metallic material of a thermal lance provides the solid fuel for the torch flame, are ignited by a substantially self-contained igniter not requiring any source of electrical energy. These torches are particularly well-suited for specialized types of manual on-site cutting or welding. The igniter is designed to be activated by sudden exposure of a pyrophoric material (disposed within the sealed interior of the igniter) to a flow of substantially pure oxygen. The igniter can be either pre-attached to an ignitable tip of the thermal lance, followed by activation (the oxygen gas flows through the interior of the lance), or simply placed on a firm surface so that an ignitable tip of the thermal lance can be used to break the seal on the igniter and thereby introduce the flow of oxygen into the interior of the igniter.

Described herein are methods for accessing a block-based storage device having a memory-mapped interface and a block interface. In one embodiment, an apparatus (e.g., block-based storage device) includes a storage array to store data and a memory-mapped interface that is coupled to the storage array. The memory-mapped interface includes memory-mapped memory space. The memory-mapped interface receives direct access requests from a host to directly access memory-mapped files. The apparatus also includes a block interface that is coupled to the storage array. The block interface receives block requests from a storage driver to access the storage array.

Copolymers having copolymerized units of vinylidene fluoride, perfluoro(alkyl vinyl) ether, 2-hydropentafluoropropene, and, optionally, tetrafluoroethylene, exhibit excellent low temperature properties and processability when cured with polyhydroxy compounds or amines.

Fluoroelastomers containing copolymerized units of vinylidene fluoride, perfluoro(alkyl vinyl)ether, 2-hydropentafluoropropene, and, optionally, tetrafluoroethylene, and having an iodine atom present at some polymer chain ends, exhibit excellent low temperature properties and processability when dual cured with both polyhydroxy compounds and organic peroxides.
