The CaO-rich portions of the systems CaO-A~203-SiO2-K2SO,, CaO-AC203-K2SO,-CaSO,, CaO-A~203-SiO2-K2SO,-CaSO, and CaO-A~203-Fe203-CaSO,-K2SO, have been studied experimentally. Schemes are presented showing phase assemblages compatible at subsolidus temperatures. Melting commences at about 825°C in as

✦ Synopsis
Hydrollen cyanide has been observed as • product from the photolysis of the CH2CO--N 2 and CH2N2-N 2 systems. The rate constant for the re.tction of CHa(XIB l) with N a has been detegmmed to be ¢10 -16 cm 3 molecule -1 s -1 . A time history of the HCN production has been obtained and s hypothesis advanced to explain its pmductlon Copyniht

In an extension of our earlier studies at lower temperatures [4,51 the title reaction was measured directly in a flow reactor at temperatures of 600 and 700 K. The pressure of 0.65 mb was chosen that low in order to reduce the contribution of the stabilization channel. OH was used in an excess over
