标题 :Silicon surface modification for the electrochemical synthesis of silicon particles in suspension
发明人：TU CHANG-CHING; TANG LIANG; VOUTSAS APOSTOLOS T

摘要:A process of silicon (Si) surface modification is provided for the electrochemical synthesis of Si particles in suspension. The process begins with a Si first substrate with a surface, and forms Si particles attached to the surface. Hydrogen-terminated Si particles are created and the first substrate is immersed in a hexane/1-octene (1/1 volume ratio) solution with a catalytic amount of chloroplatinic acid (H 2 PtCl 6 ). 1-octene is bonded with the hydrogen-terminated Si particles, creating modified Si particles, with octane capping ligands, attached to the substrate surface. The first substrate is then exposed to ultrasonication, separating the modified Si particles from the first substrate. After removing the first substrate, a suspension is created of modified Si particles suspended in excess hexane/1-octene.

标 题 :Process for the synthesis of bis(alkyl sulphide)-decaborane (12)

权利人:FRANCE ETAT
摘要:The invention relates to a process for the synthesis of bis(alkyl sulphide)-decaboranes (12). n This synthesis is characterized in that a decahydrodecaborate (2-) salt of the general formula M 2 B 10 H 10 , in which M represents a positive radical, is treated with a mixture comprising a strong oxygen-containing acid and an alkyl sulphide of the formula R 2 S, in which R is a lower alkyl radical. In a preferred procedure, the said mixture is a solution of a strong oxygen-containing acid which is saturated with an alkyl sulphide. n The bis(alkyl sulphide)-decaboranes (12) are especially useful in the synthesis of certain carboranes.

标题 :Process for the synthesis of high molecular weight predominantly amorphous polymers with improved color and adhesive properties
发明人：HOLLIDAY ROBERT E; SEEGER HORST K
权利人:EASTMAN CHEM CO
摘要:The present invention relates to a continuous high molecular weight, amorphous polymer-producing process which includes a reactor design, an unreacted monomer and solvent recycling and purification system, a catalyst deactivation and polymer stabilization system, and a polymer isolation process. The present invention relates to the discovery of a continuous process for the production of polymers. The discovery relates particularly to Ziegler-Natta synthesis of amorphous polymers from alpha -olefins. In the inventive method, it was discovered that reconfiguration of process streams for the purposes of the product stabilization and catalyst deactivation led to elimination of the need for an elaborate absorption bed train to purify recycled components. Additionally, reconfiguration of process streams resulted in an improvement of process yield where recycled solvent and unreacted monomer previously caused process yield to be marginal in comparison to using entirely new feedstocks. The present invention also comprises a preferred embodiment of the synthesis of polyoctene, the separation of polyoctene from unreacted octene monomer and unreactive hydrocarbon solvent, and the deactivation of polymerization catalyst.
