Description

D-Lactide CAS 13076-17-0

D-LACTIDE Usage

D-(+)-Propyl cross ester is a cyclic diester of lactic acid, a by-product that is produced by muscle sarcomeres and red blood cells when the body breaks down carbohydrates for energy at low oxygen levels. A suitable catalyst can be used to polymerize the propionyl ester into polylactic acid, resulting in a material with useful properties.

D-LACTIDE Storage

1. This series of products are biodegradable materials. Avoid contact with water, acidic substances, alkaline substances, alcohol reagents and other reagents that can cause product degradation during storage.

2. This series of products should be sealed and stored in a dry and low temperature (refrigerator freezing -20 degrees) during storage, and should be sealed with a sealer (the remaining products after use must not be packaged and stored in ziplock bags).

3. When in use, take it out of the refrigerator and place it at room temperature, and wait until the temperature reaches room temperature to wipe off the condensed moisture on the surface of the packaging bag before opening (the moisture in the air will condense on the surface of the product and degrade the product when it is taken out of the refrigerator without a constant temperature and opened). The air humidity of the environment during use should be less than 35% to prevent the remaining products from getting damp and affecting product quality.

D-LACTIDE Packaging

500g/Bag or 1kg/Bag or 25kg/Drum.

How to distinguish D-LACTIDE and L-LACTIDE?

1. The needle-shaped crystals of L- and D-lactide are the same, and the melting point is the same, and the appearance is indistinguishable. The racemic form can be distinguished from the appearance, and it is not needle-shaped, and the melting point is different.
2. Nuclear magnetism and infrared cannot be distinguished, optical rotation can be distinguished, left-handed is negative, right-handed is positive, racemization has no optical rotation
