Synthesis and characterization of hydrotalcites: Potential thermal stabilizers for PVC
Layered double hydroxides (LDH) are considered as a new emerging class of PVC stabilizers to replace toxic and environmentally hazardous class of heavy metals. A new series of Ca-Al-X (X=NO3 , CO3 , Cl, SO4 , PO4 ) hydrotalcites have been prepared by hydrothermal process. The hydrotalcite particles are nanosized and have been characterized by EDX, XRD, FTIR and TGA techniques. A comparative stu...
متن کاملOrganotin Compounds and the Environment
Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...

متن کاملSulfamethazine copper(ii) complexes as antimicrobial thermal stabilizers and co-stabilizers for rigid PVC: spectroscopic, thermal, and DFT studies
[CuL2(OH2)]$1.5H2O (1), [CuL2(bpy)]$0.66H2O (2) and [CuLQ(OH2)]$H2O (3) (HL 1⁄4 sulfamethazine, bpy 1⁄4 2,20-bipyridine and HQ 1⁄4 8-hydroxyquinoline) complexes were prepared, characterized (elemental analysis, infrared spectroscopy, thermogravimetric analysis, ultraviolet-visible spectroscopy, magnetic and conductivity measurement), and tested for their antibacterial activity. Coordination of ...
متن کاملOrganotin compounds: industrial applications and biological investigation.
According to Ross (1), there are three main areas in which organotin compounds have product and process utility: (1) heat stabilizers; (2) catalytic agents; (3) biocidal compounds. Organotin derivatives account for the fourth largest production of organometallics amounting to about 3-4 million pounds per year as compared with about 485 million pounds per year for organolead compounds. Originall...
