The DADC monomer is available from several manufacturers, such as PPG Industries (CR-39 ), Akzo (Nouryset 200), Enichem (RAV) Rhone-Poulenc (XR-80), Tokuyama Soda (TS-16), and Mitsui Toatsu (MR-3).

The properties and manufacturers of the commercial isocyanates are presented in Table 3. Several TDI producers, ie, AHied, Du Pont, Union Carbide, ICI, have stopped the production of TDI. Although Rhone-Poulenc has sold its TDI plants in France to SNPE, the company has made arrangements with Arco to market TDI. 

Isocyanates are now produced for Rhone-Poulenc by SNPE. A 27,000-t expansion is planned. 

There are relatively few producers of boric acid esters ia the United States. Eight domestic producers of these compounds (28) are Anderson Development Co., Akzo America, Inc., E. I. du Pont de Nemours Co., Inc., Eagle-Picher Industries, Inc., The Gas Elux Co., Morton International, Callery Chemical Co., and U.S. Borax Chemical Corp. In addition, Rhone-Poulenc Chemicals, Manchester, UK, produces commercial quantities of selected boric acid esters. 

Data on the production, sales, and value of synthetic coumarin were pubhshed by the U.S. Tariff Commission until 1967 (Table 4). Later data are not available because the number of producers dropped to three or fewer. In 1992, Rhone-Poulenc was the only coumarin producer both ia the United States and in Western Europe. Commercial quantities of coumarin have also been produced in China and, to a lesser extent, in the former Soviet Union.
