20090259065 | METHODS OF MAKING ORGANIC COMPOUNDS BY METATHESIS AND HYDROCYANATION - The invention is directed to methods of making organic compounds by metathesis and hydrocyanation. The method of the invention may be used, for example, to make industrial important organic compounds such as diacids, diesters, acid-amines, acid-alcohols, acid-nitriles, ester-amines, ester-alcohols, and ester-nitriles. | 10-15-2009 |
20090264672 | METHODS OF MAKING ORGANIC COMPOUNDS BY METATHESIS - Described are methods of making organic compounds by metathesis chemistry. The methods of the invention are particularly useful for making industrially-important organic compounds beginning with starting compositions derived from renewable feedstocks, such as natural oils. The methods make use of a cross-metathesis step with an olefin compound to produce functionalized alkene intermediates having a pre-determined double bond position. Once isolated, the functionalized alkene intermediate can be self-metathesized or cross-metathesized (e.g., with a second functionalized alkene) to produce the desired organic compound or a precursor thereto. The method may be used to make bifunctional organic compounds, such as diacids, diesters, dicarboxylate salts, acid/esters, acid/amines, acid/alcohols, acid/aldehydes, acid/ketones, acid/halides, acid/nitriles, ester/amines, ester/alcohols, ester/aldehydes, ester/ketones, ester/halides, ester/nitriles, and the like. | 10-22-2009 |
20110059146 | Antimicrobial Materials - The disclosure provides methods and materials suitable for preparing coating layers on substrates. The coatings comprise quaternary amine groups and therefore impart anti-bacterial properties to the substrate. In one embodiment, for example, there is provided a quaternary amine-containing polymeric coating comprising propylene and ethylene repeat units. | 03-10-2011 |
20120010303 | WAXES DERIVED FROM METATHESIZED NATURAL OILS AND AMINES AND METHODS OF MAKING - Wax compositions derived from metathesized natural oils and amines and methods of making wax compositions from metathesized natural oils and amines are provided. The wax compositions comprise amidated metathesized natural oils formed from a metathesized natural oil and at least one amine. The methods comprise providing an amine and providing a metathesized natural oil. The methods further comprise mixing the amine and the metathesized natural oil in the presence of a basic catalyst or heat, causing a reaction between the amine and metathesized natural oil, therein forming the amidated metathesized natural oil. | 01-12-2012 |
20150094481 | METHODS OF MAKING ORGANIC COMPOUNDS BY METATHESIS AND HYDROCYANATION - The invention is directed to methods of making organic compounds by metathesis and hydrocyanation. Hydrocyanation functions to introduce a nitrile group into the organic compound. The nitrile group may be converted into an amine group, an aldehyde group, an alcohol group, or a carboxylic acid group. The method of the invention may be used, for example, to make industrial important organic compounds such as diacids, diesters, acid-amines, acid-alcohols, acid-nitriles, ester-amines, ester-alcohols, and ester-nitriles. | 04-02-2015 |

20140293853 | METHOD FOR TRANSMITTING MACHINE TYPE COMMUNICATION DATA AND APPARATUS FOR THE SAME - A method for transmitting machine type communication (MTC) data and an apparatus therefor are disclosed. A method for transmitting data in a MTC device located in a mobile communication system may comprise estimating an absolute position of the MTC device, receiving an awake message, extracting downlink synchronization information and absolute positional information of a base station included in the awake message, estimating a transmission delay time between the MTC device and the base station, and transmitting signal to the base station based on the transmission delay time and the downlink synchronization information. Therefore, a problem of uplink interferences between terminals and a base station due to a MTC device, which can be generated in supporting MTC services for a conventional cellular communication system, may be resolved. | 10-02-2014 |
20140294107 | APPARATUS FOR MULTI-USER MULTI-ANTENNA TRANSMISSION BASED ON DOUBLE CODEBOOK AND METHOD FOR THE SAME - Double codebook-based multi-user, a multi-antenna transmission apparatus and a transmission method are started. A transmission apparatus includes an effective channel information reception unit configured to receive an effective channel matrix for a transmission channel, a zero-forcing precoding unit configured to receive data streams and perform zero-forcing precoding to null inter-user interference based on the effective channel matrix, a beam forming unit configured to receive the data streams subjected to the zero-forcing precoding from the zero-forcing precoding unit and perform beam forming, and a multi-antenna array configured to transmit the data streams subjected to the beam forming by the beam forming unit to the multi-user. With the method and apparatus, it is possible to improve a transmission capacity and effectively process an interference between terminals in a multi-layer beam forming environment. | 10-02-2014 |
