Disclosed is a method for preparing a formamide compound, the method uses carbon dioxide, hydrogen and an amine compound as raw materials and a transition metal complex as a catalyst, and the reaction is carried out in an organic solvent or in the absence of a solvent to form a formamide compound. The method of the present invention is an effective method of chemical utilization of carbon dioxide, which has the advantages of high reaction efficiency, a good selectivity, mild conditions, economic and environmental protection, being simple and convenient to operate and the like, and has a good popularization and application prospect.

Method for preparing formamide compound

An injection molding apparatus for forming a gasket around an edge of a glass is provided. The injection molding apparatus includes: an injection mold die; a fixing component, disposed inside the injection mold die and adapted for fixing the glass inside the injection mold die; a detection unit, mounted to the injection molding apparatus and adapted for detecting an image or vibration of the glass; a determination unit, coupled with the detection unit and adapted for determining whether the glass breaks based on a detection result of the detection unit. The apparatus can determine whether the glass breaks, such that the risk of scratching the injection mold die by glass breaking may be reduced. Therefore, the injection molding yield can be improved, the time for repairing the injection mold die may be reduced and a service life of the injection mold die may be prolonged.
