USES

DBI is a highly effective, halogen-free reduction inhibitor for dyeing of polyester fibers and their blends with, e.g. cellulose or viscose rayon. It protects disperse dyes from yield loss during HT exhaust dyeing processes.

The protection is particularly required when dyeing with reduction-sensitive dyes. Most disperse dyes (particularly bluish reds, blues and navies) are sensitive to reduction in fully flooded machines, where less oxygen is present in the dyebath and/or at higher temperatures than the usual 130°C.

Characteristics

Protects sensitive disperse dyes from reduction caused by some dispersing agents and substances carried into the dyebath, e.g. by cellulosic fibers

The 1,3-Dimethylurea, with CAS number of 96-31-1, can be called N,N'-Dimethylharnstoff ; N,N'-Dimethylurea ; Symmetric dimethylurea ; sym-Dimethylurea . It is a white crystal, 1,3-Dimethylurea (CAS NO.96-31-1) is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Use of 1,3-Dimethylurea:
1,3-Dimethylurea is used for synthesis of caffeine, theophylline, pharmachemicals, textile aids, herbicides and others. In the textile processing industry 1,3-dimethylurea is used as intermediate for the production of formaldehyde-free easy-care finishing agents for textiles. The estimated world production of DMU is estimated to be less than 25,000 tons.
