Abstract: The present invention relates to a method for preparing glufosinate or an analogue and an intermediate thereof. The method comprises: a) reacting a compound of formula (II), an alcohol of formula (III) and a compound of formula (V); and b) hydrolyzing the product of the reaction above to obtain glufosinate of formula (IV) or an analogue thereof.

Abstract: Disclosed are a display apparatus and a split-screen playback method. The method includes: upon receiving media data pushed from the terminal device, detecting a type of a current signal source of the display apparatus; in response to the type of the current signal source being included in a source list, starting a split-screen playback mode in the display apparatus, generating a first window and a second window, presenting the first window and the second window, on a display, and displaying video data from the current signal source in the first window and displaying the media data from the terminal device in the second window; in response to the type of the current signal source being not included in the source list, not generating the first window and the second window, and presenting the video data from the current signal source in a full-screen mode on the display.

Abstract: An aluminum borate whisker reinforced and toughened non-metallic matrix composite is provided, which specifically includes a non-metallic material reinforced and toughened with aluminum borate whiskers. The composite exhibits a higher bending strength and fracture toughness and a higher wear resistance. A method for preparing the composite is also provided. The method includes mixing the aluminum borate whiskers and the non-metallic material to form a mixture; and sintering the mixture by a vacuum hot press method, or molding the mixture.

Abstract: The present invention relates to a method for preparing glufosinate or analogues thereof.

Abstract: Provided are a method for preparing L-glufosinate and the intermediate compounds of formula (V) and formula (III).

Abstract: A preparation method for glufosinate or a salt, an enantiomer or a mixture of enantiomers in all ratios thereof, the method being especially suitable for the preparation of glufosinate, and greatly shortening steps in an existing preparation process. Especially in the preparation of L-glufosinate, the product can effectively retain the ee value of the raw materials.

Abstract: A preparation method for glufosinate ammonium or a salt thereof, an enantiomer thereof, or mixtures of the enantiomer thereof in all ratios, comprising reacting a compound of formula (II) or a salt, an enantiomer, or mixtures of the enantiomer in all ratios with one or more compounds of formula (III) or mixtures thereof.
