Abstract
Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE AMPICILINA"<D>. A invenção refere-se a um processo para a preparação de ampicilina no qual ácido 6-aminopenicilânico (6-APA) é submetido a uma reação de acilação enzimática com a ajuda de um derivado de fenilglicina, com a concentração total do 6-APA presente na mistura reacional, mais ampicilina, sendo maior que 250 mM, a concentração de 6-APA em solução sendo mantida menor que 300 mM e a razão molar do agente de acilação para 6-APA que é empregada sendo menor que 2,5. A concentração de 6-APA presente na mistura reacional na forma dissolvida pode ser mantida baixa de várias maneiras. Uma possibilidade de manter baixa a concentração de 6-APA dissolvido é inicialmente carregar apenas uma parte da quantidade total de 6-APA e adicionar o restante durante a reação. A quantidade total de 6-APA é de preferência inicialmente carregada no início da reação. Um método adequado de não obstante obter uma baixa concentração de 6-APA dissolvido é, por exemplo, manter o pH em um valor mais baixo que o pH no qual é obtida solubilidade máxima dos reactantes, garantindo que a concentração do derivado de fenilglicina seja mantida baixa, por exemplo introduzindo o derivado de fenilglicina parcialmente durante a reação, por exemplo na forma de um sal do mesmo, de preferência o sal de PGA e um ácido mineral. Desta maneira é possível, de maneira simples, obter introdução ótima do PGA mantendo o PH constante. PGA. 1/2H~ 2~SO~ 4~ é de preferência usado.
