Uso do D-LACTIDE<\/strong><\/h2>\n

O D-(+)-propionil \u00e9ster cruzado \u00e9 um di\u00e9ster c\u00edclico do \u00e1cido l\u00e1tico, um subproduto produzido pelos sarc\u00f4meros musculares e pelas c\u00e9lulas vermelhas do sangue quando o corpo decomp\u00f5e os carboidratos para obter energia em n\u00edveis baixos de oxig\u00eanio. Um catalisador adequado pode ser usado para polimerizar o \u00e9ster propion\u00edlico em \u00e1cido polil\u00e1tico, resultando em um material com propriedades \u00fateis.<\/h4>\n

<\/h4>\n

Armazenamento de D-LACTIDE<\/strong><\/h2>\n

1. Esta s\u00e9rie de produtos \u00e9 composta por materiais biodegrad\u00e1veis. Evite o contato com \u00e1gua, subst\u00e2ncias \u00e1cidas, subst\u00e2ncias alcalinas, reagentes alco\u00f3licos e outros reagentes que possam causar a degrada\u00e7\u00e3o do produto durante o armazenamento.<\/h4>\n

2. Essa s\u00e9rie de produtos deve ser selada e armazenada em local seco e de baixa temperatura (geladeira congelando a -20 graus) durante o armazenamento e deve ser selada com um selador (os produtos restantes ap\u00f3s o uso n\u00e3o devem ser embalados e armazenados em sacos ziplock).<\/h4>\n

3. Quando estiver em uso, retire-o da geladeira e coloque-o em temperatura ambiente e aguarde at\u00e9 que a temperatura atinja a temperatura ambiente para limpar a umidade condensada na superf\u00edcie do saco de embalagem antes de abrir (a umidade do ar se condensar\u00e1 na superf\u00edcie do produto e degradar\u00e1 o produto quando ele for retirado da geladeira sem temperatura constante e aberto). A umidade do ar do ambiente durante o uso deve ser inferior a 35% para evitar que os produtos restantes fiquem \u00famidos e afetem a qualidade do produto.<\/h4>\n

Embalagem de D-LACTIDE<\/strong><\/h2>\n

500g\/saco ou 1kg\/saco ou 25kg\/tambor.<\/h4>\n

 <\/p>\n

Como distinguir D-LACTIDE e L-LACTIDE?<\/strong><\/h2>\n

1. Os cristais em forma de agulha do L-lact\u00eddeo e do D-lact\u00eddeo s\u00e3o iguais, e o ponto de fus\u00e3o \u00e9 o mesmo, e a apar\u00eancia \u00e9 indistingu\u00edvel. A forma rac\u00eamica pode ser distinguida pela apar\u00eancia, n\u00e3o \u00e9 em forma de agulha e o ponto de fus\u00e3o \u00e9 diferente.
\n2. O magnetismo nuclear e o infravermelho n\u00e3o podem ser distinguidos, a rota\u00e7\u00e3o \u00f3ptica pode ser distinguida, o lado esquerdo \u00e9 negativo, o lado direito \u00e9 positivo, a racemiza\u00e7\u00e3o n\u00e3o tem rota\u00e7\u00e3o \u00f3ptica<\/h4>\n
