Ball Milling Digitalfire
Ball mills can be continuous or periodic they can be small or gigantic low speed or high speed rotated or vibrated or both for maximum efficiency a ball mill should be made of or lined with a porcelain or other very hard surface so grinding also occurs between the wall and the balls the balls should be of a range of sizes to maximize
Nucleophilic Displacement Reactions Of 5Derivatised
Nucleophilic displacement reactions of nucleoside derivatives are well established owing to the accessibility of precursor sulfonate esters and halides displacements with a diverse variety of both hard and soft nucleophiles have enabled the construction of natural products and their analogues typically such reactions require the use of highboiling dipolar aprotic solvents and anionic
