USA customers: 1-800-325-3010 orview local office numbers.
What solvents are most compatible with Product L4777, Lipase acrylic resin?
This resin works well in solvent-free reactions, as well as in inert water immiscible solvents such as petroleum ether, n-hexane and n-heptane. If the reaction being catalyzed is hydrolysis of an ester, addition of water to the reaction mix is recommended. For other reactions water is likely not required, and in some cases would actually be detrimental.
What is the substrate specificity of Product L4777, Lipase acrylic resin?
Lipase acrylic resin has a broad substrate specificity. It promotes reactions between a wide range of primary and secondary alcohols and carboxylic acids.
What are the components of Product L4777, Lipase acrylic resin, and what are the optimal recommended conditions?
This product consists of a thermostable lipase enzyme immobilized on a macroporous acrylic bead resin. The bead-shaped particles have a diameter in the range of 0.3-0.9 mm. The resin will be compatible with stearyl alcohol at temperatures of 40-60°C, which is the normal operating temperature of the enzyme. This immobilized enzyme can be used in hexane with no adverse effects.
What is the Department of Transportation shipping information for this product?
Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
