Versuchsvorschrift

In a similar manner, 634.3 parts isodecyl alcohol, 603 parts methyl methacrylate, 220.6 parts heptane, 3.1 parts dimethyltin dichloride, 1.4 parts sodium methoxide (molar ratio 1.84:1) 2.21 parts 4-methoxyphenol and 0.73 parts hydroquinone were reacted as in Example 1 to yield 185.9 parts (97.6 percent yield, based on starting alcohol) of isodecyl methacrylate having a purity of 99.0 percent and containing no detectable tin.
