Publication number: 20150112108Abstract: A method prepares high-yield adamantane in the presence of an ionic liquid catalyst formed by mixing an aluminum bromide-containing or aluminum iodide-containing catalyst and an ionic liquid. Given the method, isomerization of tetrahydrodicyclopentadiene (THDCPD) takes place in the presence of the ionic liquid catalyst to produce adamantane of high reactant conversion, high selectivity, and high yield and cut costs.Type: ApplicationFiled: May 16, 2014Publication date: April 23, 2015Applicant: NATIONAL CHUNG SHAN INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: CHI-FA HSIEH, SHU-CHEN CHIANG, WEN-CHIUNG SU, FU-YENG LIN

Patent number: 8658052Abstract: Disclosed is a method for making a highly thermally conductive composite. At first, paraffin wax is subjected to apparent modification. Expandable graphite is oxidized and organically modified. The modified paraffin wax is melted and mixed with the modified expandable graphite so that the modified expandable graphite is evenly distributed in the modified paraffin wax. With the expandable graphite, which exhibits an excellent heat transfer coefficient, the thermal conductivity of the paraffin wax is improved. The melting and solidifying rates of the paraffin wax are improved.Type: GrantFiled: August 2, 2011Date of Patent: February 25, 2014Assignee: Chung-Shan Institute of Science and Technology, Armaments, Bureau, Ministry of Naional DefenseInventors: Chi-Fa Hsieh, Fu-Yen Ling, Yeng-Fong Shih, Wei-Chen Liu

Publication number: 20130144026Abstract: Disclosed is a method form making a thermo-stable and transparent resin. In the method, at first, polyborosiloxane is syhthesized by hydrolyzing and condensing a boron-containing compound, used as a precursor, and a silane compound. Then, epoxy group-containing polyborosiloxane is synthesized by grafting an epoxy group to the polyborosiloxane. Finally, an epoxy/PGB composite is synthesized by reacting the epoxy group-containing polyborosiloxane with epoxy for consolidation, thus providing a homogenous, stable, net-shaped composite.Type: ApplicationFiled: March 9, 2012Publication date: June 6, 2013Applicant: Chung-Shan Institute of Science and Technology, Armaments, Bureau, Ministry of National DefenseInventors: Wen-Chiung Su, Chi-Fa Hsieh, Yeng-Fong Shih

Publication number: 20120101203Abstract: The invention provides a compound and method of producing the same. The method of the invention includes the following steps. First of all, Polycaprolactone (PCL), dimethylol propionic acid (DMPA), 4,4?-methylenebis (cyclohexyl isocyanate) (H12MDI), and dibutyltin dilaurate (DBT) are mixed in a solvent in the first place and a solution is formed. This solution is then mixed with triethylamine (TEA) and triethylene tetramine (TETA). After that, amino-terminated anionic waterborne polyurethane (WPU) is produced. A sol-gel process is proceeded with a mixture of amino-terminated anionic waterborne polyurethane, tetraethylorthosilicate (TEOS) without any extra catalyst, and a compound, waterborne polyurethane-silica nanocomposite materials, is eventually produced.Type: ApplicationFiled: January 1, 2012Publication date: April 26, 2012Inventors: Chi-Fa Hsieh, Jui-Ming Yeh, Tai-Kang Liu

Patent number: 8071032Abstract: The invention discloses a method and a system for manufacturing organopolysiloxane. The system comprises N raw material tanks, N gauging tanks, a first reactor, a second reactor and at least one product tanks which are arranged in order from high to low. The manufacturing method comprises the following steps of: firstly, N raw materials are added into the N raw material tanks respectively. Then, a plurality of processing parameters about the organopolysiloxane are inputted to control the N gauging tanks to measure the dosage of the N raw materials according to the processing parameters, which along with a cyclic siloxane monomer are inputted into the first reactor. The first reactor is controlled to carry on ring-opening and re-distribution polymerization equilibrium reaction to the N raw materials and the cyclic siloxane monomer, so as to generate an intermediate product, and transfer the intermediate product into the second reactor.Type: GrantFiled: June 7, 2009Date of Patent: December 6, 2011Assignee: Chung-Shan Institute of Science and Technology Armaments Bureau, Ministry of National DefenseInventors: Tai-Kang Liu, Chi-Fa Hsieh

Patent number: 7822583Abstract: A design method of batch falling strand devolatilizers is disclosed. The method includes following steps. Firstly, construct a database that contains data of batch falling strand devolatilizer vs. devolatilization of at least one kind of polymer. Then data in the database is substituted into a mass balance difference equation to get a backmixing parameter. When the backmixing parameter is zero or is approaching zero, a liquid diffusion stage efficiency equation having a film equation or a pool equation is integrated with the mass balance difference equation to get a devolatilization process efficiency equation. By optimizing of a theoretical value of the backmixing parameter, a theoretical value of the process efficiency from calculation of the devolatilization process efficiency equation approaches the value of the process efficiency.Type: GrantFiled: April 16, 2007Date of Patent: October 26, 2010Assignee: Chung Shan Institute of Science and Technology, Armaments Bureau, M.N.D.Inventors: Tai-Kang Liu, Chi-Fa Hsieh
