The optimal reaction conditionswere obtained, and structure of the product was characterized by means of IR, H NMR and ms. Thecopolymer AA/AM/4-MNDMAPN-AQ from acrylic acid( AA), acrylamide( AM)and 4-MNDMAPN-AQ was prepared. The fluorescent properties and scale inhibition performance of the copolymer werestudied in detail. Relationship between fluorescent intensity and concentration of copolymer was linearin concentration range of 1-8 mg/L. The correlation coefficient(R )was 0. 995 0. Under optimalconditions:[ Ca*]=5 mmol/L, HCO ]=10 mmol/L, I=(75+0. 2)C for 10 h and copolymermass concentration 2. 5 mg/L, the scale inhibition rate could reach 70. 78% by means of hard scaledetermination. Beside possessing fluorescence, the copolymer AA/AM/4-MNDMAPN-AQ, as a higherformance scale inhibitor, was comparable with 2-phosphono-butane-1, 2, 4-tricarboxylic acid whichwas known as the best scale inhibitorKeywords] fluorescent monomer; quaternary ammonium salt synthesis; copolymer; acrylic acidcrylamide scale inhibitor有機膦類阻垢緩蝕劑一直以來都是水處理藥劑加藥方式中因加藥不及時造成的腐蝕、結垢等問題或的核心組分,隨著環(huán)境保護要求的日益提高,低膦、無加藥過多而造成的資源浪費,實現(xiàn)了水處理藥劑的在膦藥劑成為水處理領域的發(fā)展趨勢1-。同時由于線分析和自控加藥,國內(nèi)在這方面的研究剛剛起步3處理過程中的監(jiān)控要求,傳統(tǒng)的用化學分析總磷作為中國煤化工,首先以4一氯一1,藥劑有效濃度控制指標的方法越來越不適應需要。具有熒光性能的水處理藥劑是一種示蹤型水處理劑[收CNMHG]200-11-05。[作者簡介]雷武(1971-),男湖北省武漢市人,碩士,副教投,電具有靈敏度高、檢測下限低等優(yōu)點,成為水處理領域話025-8415190,電郵leiwuhao@yahoo.com,cm。聯(lián)系人:王風的研究熱點8-18。采用示蹤型水處理劑避免了傳統(tǒng)云,電話025-84315190石油化工PETROCHEMICAL TECHNOLOGY2006年第35卷8-萘二甲酸酐和3-二甲氨基丙胺為原料,經(jīng)3步系,及其對CaCO3的阻垢分散性能。反應合成了一種水溶性的熒光單體4-甲氧基N-(2-N,N-二甲基氨基丙基)萘二甲酰亞胺烯1實驗部分丙基氯化銨(4- MNDMAPN-AQ),然后與丙烯酸1.1反應方程式(AA)和丙烯酰胺(AM)共聚,得到了一種新型多功單體4- MNDMAPN-AQ的合成反應見式能含熒光基團的共聚物(AAAM4- MNDMAPN(1);共聚物AAAM4- MNDMAPN-AQ的合成AQ)。考察了該共聚物質(zhì)量濃度與熒光強度的關反應見式(2)。CH,CH,CHIN
