Claims (4)

1.Непрерывный способ получени  метакриловой кислоты из ацетонциангидрина , от л и ч а ю щ и и с  тем, что, с целью предотвращени  полимеризации и обеспечени  проточности системы, в процессе синтеза постадийно добавл ют ингибитор.1. A continuous process for the production of methacrylic acid from acetone cyanohydrin, which is based on the fact that, in order to prevent polymerization and ensure the flow of the system, an inhibitor is added stepwise in the synthesis process. 2.Способ по п. 1, отличающийс  тем, что в стадии получени  амида метакриловой кислоты добавл ют ингибитор метиленовый голубой в количестве 0,3-0,4 г/л.2. A method according to claim 1, characterized in that in the step of preparing the methacrylic acid amide, a methylene blue inhibitor is added in an amount of 0.3-0.4 g / l. 3.Способ по п. 1, отличающийс  тем, что в стадии омылени  добавл ют комплексный ингибитор из смеси метиленового голубого (0,006%) и гидрохинона (0,08%).3. A method according to claim 1, characterized in that a complex inhibitor from a mixture of methylene blue (0.006%) and hydroquinone (0.08%) is added at the saponification stage. 4.Способ по п. 1, от л и ч а ю щ и и с   тем, что в стадии омылени  добавл ют комплексный ингибитор из смеси метиленового голубого (0,006), гидрохинона (0,08) и воздуха.4. The method according to claim 1, starting with the fact that a complex inhibitor from a mixture of methylene blue (0.006), hydroquinone (0.08) and air is added at the saponification stage.
