ⅡChemical character of DMPU

Because the carbonyl in its structure is with strongly absorb-electron  effect,so it is a kind of non-proton polarity solvent with high boiling  point,high flash point and low melting point,use conveniently for many  processing operation such as filtration,distillation,solvent extraction,and so  on;it is with very low toxicity,so the harm to human body is inappreciable,and  reduce the environment pollution;due to its very strong dissolvability,it can  dissolve organic matter,inorganic matter,resin,polymer,etc.,and activate all  kinds of reagent,mix to dissolve the other high boiling point solvents;it is  with very good stability,it is stable under the hot strong alkali and acidity  condition,it is with waterresistance and light,oxygen stability.Therefore DMPU  used for organic chemistry reaction can promote the dissolution of  reactants,quicken the reaction speed,increase the efficiency of reaction,and  substitute the bigger toxicity solvents.

ⅢApplication

DMPU used for producing the medicament preparation:the cuticle of  organism is a physiologicalbarrier,which prevent out-body matter from  entering,so the preparation for external use need to add the solvent that can  promote the skin absorption.The solvent should be accorded with the requirement  as below:active medicament can reach the harmed place quickly and credibly;no  skin irritation,no toxicity;keep the stability for long term.DMPU can resolve  many kinds of medicament,it is nearly no toxicity to human body,can meet above  requirement,so it is used as medicament dressing.The medicament made by mixing  DMPU,other dressings and medicament can promote the dissolution and mixture of  medicament,boost up the stability and passskin absorption of medicament,and  prolong the effect time of medicament.

Ⅳadvanced use
1. Proved by practice,using integrated performance of  DMPU is greatlly increased in fine chemicalindustry field,for producing  antibiotic,DMPU with high dielectric constant and high boiling point is more  suitable for synthesizing production,using DMPU is not only with lower  toxicity,but also can obviously increase the rate of finished product and reduce  the production cost.
2. Used in industry production,DMPU can substitute  caused-cancer Hexamethylphosphoramide(HMPA),that will be very good to protect  environment.

ⅤThe enterprises of using DMPU

All  kinds of chemical industry manufacture drug factory(such as antibiotic  manufacture factory),traditional chinese medicine factory,pesticide  factory,macromolecule material factory(plastic factory,dope factory),manufacture  film factory,top grade manufacture leather factory,top grade sponge factory,cell  factory,printing ink factory,writing ink factory,electron circuit clean lotion  manufacture factory and other fine chemical industry  factory.
