Abstract: Embodiments of this specification disclose payment methods, apparatuses, and devices based on near field communication, and media. The solution includes: sending, by a mobile terminal with a near field communication function, an electromagnetic signal used to trigger an NFC tag; obtaining tag information in the NFC tag in response to the electromagnetic signal, where the tag information includes payment link information; displaying, based on the payment link information, a payment page including user information of a first transaction party; obtaining payment information provided by a second transaction party based on the payment page; and sending a payment processing request including the payment information to a server, where the server is configured to complete payment based on the payment processing request.

Abstract: Disclosed is a method of preparing glufosinate, and specifically a method of preparing glufosinate represented by formula (I) or its salt or enantiomer, or a mixture of its enantiomers in any ratio, comprising a step of hydrolyzing a compound of formula (III) to generate a compound of formula (I). Due to a distinctive reaction mechanism adopted in the method of the present disclosure, a halogenated hydrocarbon by-product in the Michaelis-Arbuzov reaction can be avoided and thus the destructive impact of the halogenated hydrocarbon by-product on ozone in the aerosphere can be prevented. Accordingly, the equipment and engineering investments required for the separation, purification, and collection of the foregoing by-product are eliminated, and the potential environmental and safety hazards brought by the foregoing by-product are also avoided.
