Antitartre Azote Carbonate de calciumLe carbonate de calcium (CaCO3) est composé d'un ion carbonate (CO32-) et d'un ion calcium (Ca2+), sa masse molaire est de 100,1 g/mole.
C'est le composant principal du calcaire et de la craie, mais également du marbre. C'est aussi le principal constituant des coquilles d'animaux marins, du corail et des escargots. Fluorescence Phosphates Polyéthylène glycol d'Allyloxy

Résumé : |
Allyloxy polyethoxy ether (APEG) and succinic anhydride were used to prepare allyloxy polyethoxy carboxylate (APEL). 8-Hydroxy-1,3,6-pyrene trisulfonic acid trisodium salt (PY) reacted with allyl chloride to produce fluorescent monomer 8-allyloxy-1,3,6-pyrene trisulfonic acid trisodium salt (PA). APEL and PA were copolymerized with maleic anhydride (MA) to synthesize the PA tagged, phosphate and nitrogen free CaCO3inhibitor MA-APEL-PA. Structures of PA, APEG, APEL, and MA-APEL-PA were obtained by FT-IR and1H-NMR measurements. The observation shows that the dosage of MA-APEL-PA plays an important role on CaCO3inhibition. The effect on the formation of CaCO3was investigated by a combination of scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) analysis. The relationship between MA-APEL-PA’s fluorescent intensity and its dosage was also studied. Correlation coefficient “r” of MA-APELPA’s fluorescent intensity and its dosage is 0.9997. MA-APEL-PA can be used to measure accurately the polymer consumption on line besides providing excellent CaCO3inhibition. |
