Summary Studies of the high-temperature photolysis of acetone have shown that methyl radicals do not initiate a chain decomposition of the acetone at temperatures below 400". 2. The acetone-sensitized photo-decomposition of dimethyl ether has been investigated over a range of pressures, temperatures and light intensities. The rate of decomposition of the ether was proportional to the square root of the absorbed light and to the first power of the ether ...
