Route of Synthesis (ROS) of Stearyl methacrylate (SMA) CAS 32360-05-7

Conditions	Yield
With 10H-phenothiazine; hydroquinone at 110 – 130℃; for 4.5h; Reagent/catalyst;	96%
In toluene at 110 – 120℃; Experimental Procedure General procedure: The initial monomers used in the production of PPDs were alkylmethacrylate (RMC), VA, and N-phenylmethylpropionamide(NPM). Fig. 1 shows their synthetic routines. The RMC monomerswere synthesized by esterification reaction. Methacrylic acid andn-alkyl alcohol at a molar ratio of 1:1.2 were dissolved in toluene,and the reaction was performed at 110 C-120 C for 4 h. The catalystwas p-toluene sulfonic acid (0.1 % by weight), and the polymerizationinhibitor was hydroquinone (0.05 % by weight). Theobtained esterified product was washed with an aqueous NaOHsolution, and finally washed with distilled water to neutrality. Inaddition, the NPM monomers were prepared by acylation reactionof aniline and methacryloyl chloride at a molar ratio of 1.2:1. Thesolvent (N, N-dimethylformamide) and acid binding agent (anhydrouspotassium carbonate) were added and reacted at room temperaturefor 2 h.
