Patent number: 11939280Abstract: A method for preparing isophorone diisocyanate by (1) reacting isophorone with hydrogen cyanide in the presence of a catalyst to obtain isophorone nitrile; (2) reacting the isophorone nitrile obtained in step (1) with ammonia gas and hydrogen in the presence of a catalyst to obtain isophorone diamine; and (3) subjecting the isophorone diamine to a phosgenation reaction to obtain the isophorone diisocyanate, wherein the content of impurities containing a secondary amine group in the isophorone diamine that undergoes the phosgenation reaction in step (3) is ?0.5 wt. The method reduces the content of hydrolyzed chlorine in the isophorone diisocyanate product, improves the yellowing resistance of the product, and the harm due to presence of hydrolyzed chlorine in the product is reduced.Type: GrantFiled: December 25, 2018Date of Patent: March 26, 2024Assignee: WANHUA CHEMICAL GROUP CO., LTD.Inventors: Yong Yu, Yonghua Shang, Lei Zhao, Wenbin Li, Ye Sun, Wei He, Xuelei Cui, Jingxu Wang, Degang Liu, Yuan Li

Patent number: 10548769Abstract: Provided is a glaucoma valve, a casing for containing a glaucoma valve and a glaucoma drainage device including the glaucoma valve and/or the casing. The valve includes a flow channel having an inlet and an outlet and a valve member connected to the outlet of the flow channel. The valve member may be formed from a degradable polymer or a combination of degradable polymer and non-degradable polymer. The valve may have a first flow channel, the interior of which may be coated with a degradable polymer, such that in use, the polymer degrades to allow a greater flow of fluid through the flow channel. The valve may include a second flow channel, which may be arranged in parallel to the first flow channel. The casing may be formed from a degradable polymer, such as a biodegradable polymer.Type: GrantFiled: August 12, 2011Date of Patent: February 4, 2020Assignees: NANYANG TECHNOLOGICAL UNIVERSITY, SINGAPORE HEALTH SERVICES PTE LTD.Inventors: Subramanian Venkatraman, Lei Shang, Yin Chiang Freddy Boey, Tina Wong
