Study on Preparation of Oxidized Starch Using Abandoned Liquid Propellant (HNO_3-27S) as Materials

摘要

Using the abandoned nitric acid-27S and starch to produce oxidized starch as water treatment agent. Water and CCl_4 are used respectively as dissolving agents to produce the oxidized starch, and the organic function groups of polyglucosans and polycarboxylic are analyzed by the basic analysis method of chemistry and the modern instrument method respectively. According to the experiment, the product either made by water or by CCl_4 as dissolving agent has the higher content of polycarboxylic. The product has high scale inhibitory effects, the scale inhibitory rate can attain to 100%.
