Patent number: 11566181Abstract: A process for producing a surfactant having two head groups and a single tail group per molecule, including steps of: producing a compound of Formula (1) from ethanol and carbon disulfide; producing a compound of Formula (2) from a carboxylic acid and bromine; producing a compound of Formula (3) from the compound of Formula (2) and methanol; producing a compound of Formula (4) from the compound of Formula (1) and the compound of Formula (3); and producing a compound of Formula (5) from the compound of Formula (4) by a direct oxidation process or by a peracid oxidation process. The surfactant produced by the process has lower critical micelle concentration and enables a lower surface tension of a liquid as compared with prior surfactants with two head groups per molecule, thereby enabling the amount of surfactant required and thus the cost to be substantially reduced.Type: GrantFiled: July 2, 2021Date of Patent: January 31, 2023Assignee: TARIM UNIVERSITYInventors: Jianhui Jiang, Yuan Zhang, Yuhui Liu, Shiwei Jiang, Fei Ren, Yanxia Yang, Shaozhen Qi

Publication number: 20160110005Abstract: A tapping control method and a terminal, which relate to the communications field and can avoid frequent automatic setting of the terminal caused by an unconscious operation of a user, thereby implementing accurate operation control on the terminal and improving a capability of the terminal to interact with the user. A specific solution is as follows. The terminal detects a tapping trigger signal within a preset frequency range by using a shock sensor; after the tapping trigger signal is detected, identifies a tapping action type corresponding to the tapping trigger signal; acquires a tapping response event that matches the identified tapping action type; and executes the tapping response event. The present disclosure can be used in a process of operation control on the terminal.Type: ApplicationFiled: December 22, 2015Publication date: April 21, 2016Inventors: Hang Yin, Jianhui Jiang, Zejin Guo, Yimai Guan, Gang Wu, Liping He, Ting Wang, Hao Wu, Yi Pan, Xu Chen, Jie Xu, Jin Wang, Zhihua Luo, Bin Wu, Huimin Zhang, Feng He, Ping Zhou
