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(jī)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(shí)造成的腐蝕、結(jié)垢等問題或的核心組分,隨著環(huán)境保護(hù)要求的日益提高,低膦、無加藥過多而造成的資源浪費(fèi),實(shí)現(xiàn)了水處理藥劑的在膦藥劑成為水處理領(lǐng)域的發(fā)展趨勢(shì)1-。同時(shí)由于線分析和自控加藥,國(guó)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(xué)分析總磷作為中國(guó)煤化工,首先以4一氯一1,藥劑有效濃度控制指標(biāo)的方法越來越不適應(yīng)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(jiǎn)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(cè)下限低等優(yōu)點(diǎn),成為水處理領(lǐng)域話025-8415190,電郵leiwuhao@yahoo.com,cm。聯(lián)系人:王風(fēng)的研究熱點(diǎn)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(duì)CaCO3的阻垢分散性能。反應(yīng)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(shí)驗(yàn)部分丙基氯化銨(4- MNDMAPN-AQ),然后與丙烯酸1.1反應(yīng)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(yīng)見式能含熒光基團(tuán)的共聚物(AAAM4- MNDMAPN(1);共聚物AAAM4- MNDMAPN-AQ的合成AQ)?？疾炝嗽摴簿畚镔|(zhì)量濃度與熒光強(qiáng)度的關(guān)反應(yīng)見式(2)。CH,CH,CHIN
