چکیده
|
A series of 5-alkylidene meldrum's acid derivatives were prepared by knovenagel condensation of meldrum's acid with different aldehydes in the presence of pipridin as a catalyst. the prepared compounds were characterized by ft-ir, 1hnmr, and 13cnmr. each prepared compound (0.2% wt. /wt.) was blended with base sixty stock lubricating oil to be evaluated as anti-rust and anti-corrosive additives according to astm-d665, and astm-d130 respectively. the formulated blend of some compounds showed better anti-rust and anti-corrosion properties compared with the base oil (blank) supplied by the midland refineries company/iraq.
