Preparation and Properties of Polyether Scale Inhibitor Containing Fluorescent Groups

摘要

Water soluble fluorescent monomer, 8-allyloxy-1,3,6-pyrenetrisulfonic acid trisodium salt (AP), was synthesized from 8-hydroxy-1,3,6-pyrenetrisulfonic acid trisodium salt and allyl chloride. AP-tagged copolymer maleic anhydride (MA)-ammonium allyl polyethoxy sulfate (APES)-AP, which is a calcium phosphate inhibitor, was prepared and the structures of AP and MA-APES-AP were characterized by FTIR and 1H-NMR. The influence of the mole ratio of MA:APES on a calcium phosphate inhibitor of MA-APES-AP was discussed. Fluorescent properties and scale inhibition performance of MA-APES-AP were also studied. The results indicate that monomer ratio has great impact on the performance of MA-APES-AP. Fluorescent intensity increases with the concentration of MA-APES-AP, with a correlation coefficient (r) of 0.9934 and MA-APES-AP limit of detection of 1.72 mg · L−1. Calcium phosphate inhibition performance test results show that calcium phosphate inhibition of MA-APES-AP reaches 98.78 percent when the dosage is 12 mg · L−1 at 80°C.View full textDownload full textKeywords8-allyloxy-1, 3, 6-pyrenetrisulfonic acid trisodium salt, ammonium allyl polyethoxy sulphate, calcium phosphate, fluorescent, polyetherRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00914030801962988
