---|---|---|
80% | With 2,6-di-tert-butyl-4-methyl-phenol; N,N'-diphenyl-1,4-phenylenediamine;Purification / work up; | A crude reaction mixture comprising 3-methacryloyloxypropylsilane was obtained as in example 1, except that 1000 ppm of 2,6-di-tert-butyl-4-methylphenol and 500 ppm of N,N'-diphenyl-p-phenylenediamine were used instead of 4,4'-methylenebis(2,6-di-tert-butylphenol). After removal of the acetone, 1 kg of this crude product was distilled through a distillation head at 3 mbar (boiling point 103 C.). After 80% of the expected product were obtained, the distillation was stopped since the bottom product of the distillation had gelled. The product obtained had a purity of 99.3%, an APHA color number of 35 and a GC content of 0.09% of 2,6-di-tert-butyl-4-methylphenol. In addition, the product had an unpleasant, fishy odor. This example shows that, in addition to the volatility of the one polymerization inhibitor, the use of a nonvolatile amine polymerization inhibitor is also disadvantageous, owing to discoloration of the product and an unpleasant odor. |
30% | With 2,6-di-tert-butyl-4-methyl-phenol;Purification / work up; | A crude reaction mixture comprising 3-methacryloyloxypropylsilane was obtained as in example 1, except that 1000 ppm of 2,6-di-tert-butyl-4-methylphenol were used instead of 4,4'-methylenebis(2,6-di-tert-butylphenol). After removal of the acetone, 1 kg of this crude product was distilled through a distillation head at 3 mbar (boiling point 103 C.). After 30% of the expected product were obtained, the distillation was stopped since the bottom product of the distillation had gelled. The product obtained had a purity of 99.3%, an APHA color number of 15 and a GC content of 0.11% of 2,6-di-tert-butyl-4-methylphenol. This example shows that the high volatility of the polymerization inhibitor not according to the invention leads to a loss of product. |
With N,N-dimethyl-(3,5-di-tert-butyl-4-hydroxybenzyl)amine;Purification / work up; | A crude reaction mixture comprising 3-methacryloyloxypropylsilane was obtained as in example 1, except that 1000 ppm of 2,6-di-tert-butyl-4-(N,N-dimethylaminomethyl)phenol were used instead of 4,4'-methylenebis(2,6-di-tert-butylphenol). [0036] After removal of the acetone, 1 kg of this crude product was distilled through a distillation head at 3 mbar (boiling point 103 C.). The product obtained had a purity of 99.5%, an APHA color number of 40 and an unpleasant fishy odor. This example shows that the use of an amine-containing phenolic polymerization inhibitor is disadvantageous owing to discoloration of the product and an unpleasant odor. |
Practical Example 4. A reaction was carried out under the same conditions as in Practical Example 1, except that 0.06 g (0.0005 mole) of 1.5-diazabicyclo [4.3.0]-non-5-ene were used as a catalyst. The yield of gamma-methacryloxypropyl trimethoxysilane after a 2-hour reaction was 93%. | ||
