摘要

以4-溴-1

8-萘二甲酸酐和N -甲基哌嗪为原料，合成得到一种新的荧光单体4-(N′-甲基-1-哌嗪基)- N-丁基-1

8-萘二甲酰亚胺烯丙基氯季铵盐(FC)。通过红外光谱、核磁共振及元素分析对FC进行了表征。将FC与丙烯酸(AA)，2-丙烯酰胺基-2-甲基丙磺酸(AMPS)，次亚磷酸钠共聚制备了含荧光基团的AA-AMPS共聚物(FC-POCA)。对该共聚物的荧光性质和阻垢性能进行了研究，结果表明：共聚物的荧光强度与其质量浓度呈良好的线性关系，线性相关系数为0.9578，检测下限为0.65 mg·L-1;采用静态法，当药剂量为20 mg·L-1时对碳酸钙阻垢率可达77.2%，当药剂量为25 mg·L-1时对硫酸钙阻垢率已经达到100%，与市售的POCA相当，达到了阻垢剂的阻垢分散性能要求。通过扫描电镜观察发现FC-POCA对CaCO3垢既有较强的分散作用又具有明显的晶格畸变能力。

Abstract

A novel water soluble fluorescent monomer

4-(N′-methyl-1-piperazinylallyl)-N-butyl-naphthalimide allyl chloride quaternary ammonium salt (FC) was synthesized from 4-bromo-1

8-maphthalic anhydride and N-methylpiperazidine.Its structure was characterized by IR

1H NMR and elemental analysis.The 2-acrylamido-2-methyl-propanesulfonic acid /acrylic acid copolymer containing fluorescent group (FC-POCA) was prepared by copolymerization of FC

acrylic acid (AA)

2-acrylamido-2-methyl-propanesulfonic acid(AMPS) and NaPO3.The fluorescence and scale inhibition performance of FC-POCA was investigated.The relationship of fluorescence intensity and concentration of FC-POCA was linear

and the correlation coefficient (R) was 0.9578，and the limit of detection was 0.65 mg·L-1.By the static method

the scale inhibition ratio of CaCO3 was 77.2% when the copolymer concentration was 20 mg·L-1，scale inhibition ratio of CaSO4 was 100% when the copolymer concentration was 25 mg·L-1.The results by SEM showed that the copolymer had high performance of scale inhibition on both dispersion and lattice distortion of CaCO3.
