摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

摘要:An organic synthesis of materials to achieve removal of low molecular weight ionic species, such as transition metal ions including cobalt, iron, nickel, and zinc, from aqueous solutions. The synthesis includes the steps of providing a cation exchange resin, functionalizing the cation exchange resin using a chloride intermediate to form a sulfonyl chloride resin, and reacting a multi-amine based ligand with the sulfonyl chloride resin to form a sequestration resin. The synthesis further includes the steps of cooling the sequestration resin, and washing and drying the sequestration resin.

标题:Method and synthesis of initiators for telechelic polyisobutylenes

摘要:A new methodology for the synthesis of a novel difunctional- and a known trifunctional initiator, i.e., 1,3-di(2-methoxy-2-propyl)-5-isopropyl benzene and 1,3,5-tri(2-methoxy-2-propyl)benzene, respectively, for the preparation of di- and tri-telechelic polyisobutylenes. The synthesis proceeds in three steps: 1) catalytic peroxidation of 1,3,5-triisopropylbenzene, 2) reduction of the peroxides to the corresponding alcohols, and 3) methylation of the alcohols. By controlling the conversion of the key peroxidation step the relative ratio of di- and tri-functional intermediates can be controlled. By the use of the 1,3-di(2-methoxy-2-propyl)-5-isopropyl-benzene, well-defined di-methoxy telechelic polyisobutylenes can be synthesized. Although the overall combined yield of the two initiators was only 14-20%, because of the low cost of the starting material, reagents used, and simple manipulations these compounds represent the most cost effective initiators to-date for the preparation of telechelic polyisobutylenes.

摘要:A method for synthesis of secondary alcohols is provided for pharmaceutical secondary alcohol by addition of organoboronic acids with aldehydes in presence of the cobalt ion and bidentate ligands as the catalyst. In addition, an enantioselective synthesis method for secondary alcohols is also herein provided in the present invention. The present invention has advantages in using less expensive cobalt ion and commercially available chiral ligands as the catalyst, wide scope of organoboronic acids and aldehydes compatible with this catalytic reaction and achieving excellent yields and/or enantiomeric excess.

摘要:As synthesized by conventional technique, zeolite ZSM-5 crystals are cubic with some twinning and measure in size over the range of from about 3 × 3 microns to about 8 × 8 microns. By synthesizing crystalline aluminosilicate zeolite ZSM-5 according to the present method, i.e. in the presence of a tetraureacobalt (II) complex and with a specifically defined reaction mixture composition, the crystalline product will consist of highly twinned rectangular prismatic crystals exhibiting extreme uniformity in size of from about 5 × 10 microns to about 10 × 20 microns, depending on the ratio of said tetraureacobalt (II) complex to silica in the zeolite synthesis reaction mixture. Synthesis of ZSM-5 in accordance hereto will provide a zeolite with enhanced catalytic activity for certain chemical reactions.
