Research on the Key Technology of Polynaphthalene Sulphonate Preparation
Industrial naphthalene is the main material for the polynaphthalene sulphonate production, domestic industrial naphthalene supply is unable to meet increasing demand of the market, and has to be always relying on imports, the price is greatly impacted by overseas market price change, for recent years, industrial naphthalene price has been increasing all the time, therefore how to reduce the consumption of industrial naphthalene has be a current scientific and production subject. This project is based on the normal production process, given the key problems of low sulphonation level, poor polymerization of polycondensate and quick slump loss of polynaphthalene sulphonate during the polynaphthalene sulphonate production, provides some specific research and improvement and which proves to be satisfactory.
