Publication number: 20240121233Abstract: The present embodiments relate to systems and methods for automatic sign in upon account signup. Particularly, the present embodiments can utilize a federated login approach for automatic sign in upon account signup for a cloud infrastructure. Specifically, the signup and sign in service (also known as SOUP) and an identity provider portal can be configured such that the nodes are aware of each other as Security Assertion Markup Language (SAML) partners. After new account registration, the signup service can redirect the user browser to a cloud infrastructure console to start with a federated login flow, where a sign in service can issue a SAML authentication request, and redirects it to signup service. Responsive to validating the browser using a SAML authentication process, the browser can be automatically signed into the new account and allowed access the account relating to the cloud infrastructure service.Type: ApplicationFiled: December 18, 2023Publication date: April 11, 2024Applicant: Oracle International CorporationInventors: Chuang Wang, Girish Nagaraja, Ghazanfar Ahmed, Divya Jain, Weisong Lin, Zheng Guo, Roberto Anthony Franco, Philip Kevin Newman

Patent number: 11845831Abstract: Related are a high-molecular weight allyl alcohol polyoxyethylene polyoxypropylene ether and a preparation method. During preparation, an allyl alcohol raw material and a supported catalyst Rb-NHPA are firstly added into a high-pressure reaction kettle, and it is heated after being replaced with a nitrogen gas; then after the internal temperature of the reaction kettle is raised to a reaction temperature, an ethylene oxide (EO) and propylene oxide (PO) mixture is continuously fed for a reaction; and finally, after the internal temperature of the reaction kettle is reduced, an acetic acid is dropwise added into the reaction kettle so that the crude product of the high-molecular weight allyl alcohol polyoxyethylene polyoxypropylene ether is neutralized to be neutral. The refining process of a polyether is omitted, the process flow is greatly simplified, and the process time is effectively saved. In addition, the supported catalyst Rb-NHP may be recycled.Type: GrantFiled: December 6, 2022Date of Patent: December 19, 2023Assignees: Zhejiang Huangma Technology Co., Ltd., Zhejiang Huangma Shangyi New Material Co., Ltd., Zhejiang Lukean Chemical Co., Ltd., Shangyu Huangma Surface Activated Reagent Research Institute Co., Ltd.Inventors: Weisong Wang, Yifeng Jin, Majishi Wang, Dinglian Ma, Ran Kou, Hongjun Gao, Qingmei Wan

Publication number: 20230303769Abstract: The present invention relates to a method for preparing a polyether amine catalyst, and polyether amine. A polyether amine catalyst is a supported metal catalyst; ?-Al2O3 is used as a carrier; basic cupric carbonate, basic nickel carbonate and basic cobalt carbonate are used as precursors of supported metals; and the polyether amine catalyst is prepared by performing twice adsorption roasting and once reduction by means of an equivalent-volumetric impregnation method. Easier decomposition is achieved by using basic carbonate, and only water and carbon dioxide are generated, such that processes and costs for treating waste gases can be saved. By using the polyether amine catalyst to prepare polyether amine, a conversion rate and primary amine selectivity can be improved, and the color of products can be reduced. Therefore, the obtained polyether amine can have higher activity and wider application.Type: ApplicationFiled: December 6, 2022Publication date: September 28, 2023Inventors: Weisong Wang, Majishi Wang, Jiang Yu, Shengli Wang, Yifeng Jin, Shicong Zhao, Minggui Song

Publication number: 20230174714Abstract: The present invention relates to a supported catalyst used for synthesizing polyether amine, a preparation method, and an application. The supported catalyst introduces Mo and CeO2 into Ni and Cu active components. By means of the cooperation of Ni, Cu and Mo, CeO2 and Ni form more active sites, such that the supported catalyst can have high reaction activity and selectivity. By using the supported catalyst to synthesize polyether amine, the amination efficiency and selectivity of polyether polyol can be greatly enhanced, thereby preparing the polyether amine with light color and narrow molecular weight distribution. In addition, the cost of the catalyst can be reduced, a process condition is relatively mild, and the disadvantage of low reaction activity of a nickel-based catalyst in synthesizing small molecule polyether amine can be overcome, such that the supported catalyst has a desirable industrial application prospect.Type: ApplicationFiled: November 30, 2022Publication date: June 8, 2023Inventors: Weisong Wang, Xinrong Wang, Yifeng Jin, Shengli Wang, Jiang Yu, Shicong Zhao, Baocheng Qiu
