Stable tolylene diisocyanate compositions |
| abstract |
A process for preparing a tolylene diisocyanate (TDI) composition containing about 5-19 percent by weight nominal TDI trimer and having improved stability by heating a TDI composition containing about 25-40 percent nominal TDI trimer and an amount of TDI dimer such that the dimer/trimer ratio is greater than about 0.14 at a temperature of at least about 130* C. until the dimer/trimer ratio is less than about 0.14 and diluting the resulting composition with a monomeric TDI composition to achieve a nominal trimer concentration of about 5-19 percent. |
