Abstract

The invention discloses a synthesis process of tridemorph, which comprises the following steps: adding tridecanol and a catalyst into a reactor together, and carrying out air replacement with nitrogenand hydrogen respectively; heating the reaction kettle to 180-200 DEG C, and reducing the catalyst for 30 minutes; heating the raw materials to 200-280 DEG C and dropwise adding 2,6-dimethylmorpholine; then continuously controlling the temperature to be 200 to 280 DEG C until the reaction endpoint is reached; standing and settling the material obtained by the reaction for 8 hours, and separatingthe catalyst; and rectifying the separated filtrate to obtain the finished product tridemorph. According to the invention, tridecanol is adopted as a main raw material, and the raw material cost has great advantages; the preparation method is simple, the technological process is short, the tridecanol and 2,6-dimethylmorpholine are adopted for one-step reaction under the action of a catalyst, the equipment investment is small, and operation is easy and convenient; in addition, the method is high in process yield and less in pollution, and a small amount of generated high waste can be used as fuel.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, in particular to a synthesis process of tridemorpholine. Background technique [0002] Tridemorpholine (N-isotridecyl 2,6-dimethylmorpholine), as a good systemic fungicide, has both eradication and protection effects, can be absorbed through leaves and roots, and is produced by ten The preparation made of trimorpholine can be used to prevent and control powdery mildew of cereal crops, coccicum solmonicolor on banana trees, caticum solmonicolor on tea trees, especially Hevea spores and Exibasidium destructor on rubber trees, and has a wide range of uses . At present, tridemorpholine products and preparations in the world are mainly produced by BASF Company, and its production scale is relatively large. It has passed the pilot test identification in Liaoning Chemical Industry Research Institute in China. The synthesis method is as follows: using tridecyl alcohol and halogenating agent as raw mate...
