Synthesis
Condensation of diethylfumarate and diethylmalonate to propane-1,1,2,3 tetracarboxylate. Catalyst specifications: Catalytic entity: Ph(CH2)-N+(PhmSO3-)3 · EtO- (1 milieq of EtO-), additive:: Sodium meta silicate 1 gm, Support: Charcoal 5 gm, Group IIA metal salt: Barium hydroxide, Method of preparation: Deposition precipitation. Procedure: in a 100-ml flask fitted with an efficient reflux condenser, magnetic stirrer bar and dropping funnel was charged 5 gm of catalyst. With stirring 1.6 g (0.001 mol) diethylmalonate and 25 ml dry ethanol was added. Reaction mixture was warmed and 1.4 gm (0.0081 mol) diethyl fumarate was added. Mixture was refluxed for 8 hours. Reaction mixture was cooled and suspension was centrifuged to recover catalyst. Analysis of reaction liquid indicated 90 % conversion for diethylmalonate. Product was distilled under vacuum 8 mm at 180-190°C to obtain propane-1,1,2,3 tetracarboxylate 85% yield. Catalyst was recovered and washed with ethanol, diethyl ether and dried under vacuum. Catalyst was recycled to obtain equivalent activity.
Check Digit Verification of cas no
The CAS Registry Mumber 635-03-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 635-03:
(5*6)+(4*3)+(3*5)+(2*0)+(1*3)=60
60 % 10 = 0
So 635-03-0 is a valid CAS Registry Number.
