6-Amino-1,3-Dimethyluracil

6-Amino-1,3-dimethyluracil Application:

6-Amino-1,3-dimethyluracil(DMAU), in pharmaceutical industry, use it in synthesis of Theophylline and etc.; 

also can be widely used as ingredient for PVC heat stabilizer;

Product Operating Principle

1. A.Mechanism:

with melting point of more than 290degC, loss on drying under 200degC of less than 1%, it suits for 

PVC’s producing process. Can absorb HCl which is by-produced during producing process of PVC, can replace Cl- which is not stable. When be used with 

ZnSt2, can react with ZnCl2 to create metal complex, then ZnCl2 losses its activity, so can avoid PVC’s 

color from changing into darker, improve PVC’s long term stability; Its basic chemical structure ‘uracil’ is 

one of the essential nucleotides of the human body, has no hazardous to human; So it is taken as PVC 

heat stabilizer of high-efficiency and safety;

1. B.DMAU and ZnSt2:

Stabilizer of DMAU/ZnSt2 is better than stabilizer of CaSt2/ZnSt2 on both initial whiteness and long term 

stability; DMAU/ZnSt2 is of systematic stability, its efficiency is better than that of CaSt2/ZnSt2, which is 

of synergistic stability;

1. C.DMAU and Hydrotalcite(or Aluminosilicate):

To add 3-4% of DMAU and 8-10% hydrotalcite(or Aluminosilicate, whose cost is lower) into Calcium/Zinc stabilizer, it can improve 

PVC’s initial colorless, and is more economic;

1. D.DMAU and Stearoyl benzoyl methane:

DMAU can improve PVC’s initial colorless and long term heat stability, so is Stearoyl benzoyl methane;

 when preparing PVC stabilizer, DMAU can replace stearoyl benzoyl methane, DMAU can be used together 

with stearoyl benzoyl methane also;

1. E.History of DMAU:

The world main producers of PVC stabilizer are cooperating with us. Accompany more and more countries

 forbid to use lead salts PVC stabilizer, it will be used more and more widely; We are the leading 

manufacturer of DMAU.
