Yield: 1320.4 g

Reaction Conditions:

with methacryloyl anhydride;2,4-dimethyl-6-tert-butylphenol;sodium methylate in methanol at 60 - 90; for 6 h;Reagent/catalyst;

Steps:

1 Example 1
Example 1Sodium Methacrylate Catalyst Generated in situ10045] Apparatus: 2 1 four-necked round-bottom flask with mechanical stirring, reflux condenser, air inlet, PtiOO temperature sensor, oil bath.10046] Batch: 1.5 mol (297.9 g) of 4-hydroxybenzophe- none, 1.65 mol (270.3 g) of MAAH, 0.0087 mol (1.6 g) of NM3O solution, 399 mg of 2,4-dimethyl-6-tert-butylphenol (Topanol A);10047] Preparation of a 30% strength solution of 4-(meth- acryloyloxy)benzophenone in MMA: Addition of a total of 772 g of MMA10048] Theoretical yield of 4-(methacryloyloxy)benzo- phenone: 399 g10049] Procedure: 4-Hydroxybenzophenone was weighed out, and 126 g of the subsequently required MMA were added; a readily stirrable composition was formed. Then IVL&AH, Topanol A stabilizer and NM3O catalyst were added, air was introduced, and the batch was heated to 90° C. The course of the reaction was monitored by gas chromatography (a sample (approximately 1.5 ml) taken, diluted with approximately 5 ml of acetone, and filtered). After a total of 5 h at 90° C., the batch was cooled to 60° C., 30 g of methanol were added for conversion of the remaining MAAH, and the batch was stirred 60° C. for 1 h. The remainder of the MMA (646 g) was then added to the batch, to produce a 30% strength solution. After cooling with accompanying stirring, filtering took place through a pressure filter with Seitz Ti000 filter layer (014 cm). Yield:1320.4 g
