3-Aminophenol → HCID 20428218, compound

Participants

Reaction Steps

The process of Example XIX was again practiced except that 59.95 parts of m-aminophenol was substituted for the p-aminothiophenol and 78.9 parts of Bis-(chloropropyl)tetramethyldisiloxane was substituted for the Bis-(chlorobutyl)tetramethyldisiloxane, and the phase transfer catalyst was 3 grams of 18 crown -6 ether. The end product was recovered at a temperature within the range of from 245° C. to 260° C. at from 0.5 mm to 2.0 mm of mercury. The recovered product was identified as Bis-(m-aminophenoxypropyl)tetramethyldisiloxane. The recovered product material was a pale yellow liquid which did not solidify upon standing in the cold at 0° C. for 3 days. Its purity, as determined by titration with perchloric acid, was better than 99%.
