benzene, 1-(isocyanatomethyl)-2-methoxy- - Introduction
2-Methoxybenzyl isocyanate(2-Methoxybenzyl isocyanate) is an organic compound with the chemical formula C9H9NO2. It has a colorless to pale yellow liquid with a strong pungent odor.
The main use of 2-Methoxybenzyl isocyanate is as an intermediate in organic synthesis. It can be used to synthesize various compounds containing isocyanate groups, such as polymers, drugs and pesticides. It can also be used as an additive for surface coatings, plastics, rubber, etc.
The preparation of 2-Methoxybenzyl isocyanate is usually obtained by reacting 2-methoxyphenylmethylamine with a cyanate ester. The specific procedure is to dissolve 2-methoxyphenylmethylamine in a suitable solvent, add the cyanate ester, then heat the reaction, and finally purify the product by distillation.
2-Methoxybenzyl isocyanate need to pay attention to safety during use. It is irritating and may be harmful to the skin, eyes and respiratory tract. Personal protective measures such as protective gloves, safety glasses and masks should be used when touching. Avoid inhaling its vapor during operation and maintain good ventilation conditions. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help. In addition, 2-Methoxybenzyl isocyanate should be protected from contact with strong oxidants and strong acids to avoid dangerous reactions.
