An efficient method for the synthesis of organic sulfonic acid potassiums containing dithiocarbamate side chains was developed through the reaction of amines, carbon disulfide and sultones in the presence of K3PO4 in water at room temperature. The organic sulfonic acid potassium derivatives are easily transformed into the corresponding organic sulfonic acids, which were further reacted with amines...
Collision detection algorithm can improve the realistic and immersion of 3D scene, is becoming one of the researches in the field of Virtual Reality. At present, in large and complex scenes, traditional collision detection algorithms exist the problems of low detection efficiency and poor accuracy. In view of above question, this paper manage to combine the Sphere with the OBB method, that is, first...
