Nasa scientists had anticipated that the impact would throw up a six-mile-highcloud of lunar dust and rock which could be scanned for evidence of frozen water.
The atmospheric radiative heating and cooling rates are calculated when one layer highcloud or low cloud appears or two layers of cloud appear simultaneously in plain and plateau areas.
The polyoxyethylene alkyl phenyl ether obtained by calcium oxide catalyst had perfect quality with narrow molecular weight distribution, highcloud point, good appearance and low by - product PEG.
