发明名称	Processo para fabricar um b-hidroxinitrilo solúvel em água
摘要	"PROCESSO PARA FABRICAR UM <225>-HIDROXINITRILO SOLúVEL EM áGUA". Um processo para fabricar um <225>-hidroxinitrilo solúvel em água. Um 1,2-epóxido e um sal de cianeto inorgânico são reagidos em um solvente tendo metanol aquoso e um tampão para formar um <225>-hidroxinitrilo. O tampão substancialmente impede a formação de produtos de reação exceto <225>hidroxinitrilo. Opcionalmente, água pode ser removida do <225>hidroxinitrilo por destilação azeotrópica com acetonitrilo e subseq³entemente purificada por meio de filtração e destilação à vácuo.
