Customer Review

Based on 1 Customer Validation

Calcium oxide is a heterogeneous base catalyst. Calcium oxide can not only be extracted from waste materials such as oyster shells, eggshells, and crab shells, but also has the ability to tolerate low to moderate oil quality, free fatty acid, and moisture content in raw materials. Calcium oxide can be used for biodiesel production, effectively catalyzing the transesterification of vegetable oils or animal fats to produce alkyl esters.

Biological Activity

Description

In Vitro

Calcium oxide catalyzes the transesterification of sunflower seed oil, achieving a biodiesel yield of 94 wt.%, and can be reused for up to 8 cycles with a minimum yield still reaching 73 wt.%^[1].
Calcium oxide catalyzes the transesterification of pure soybean oil, achieving a biodiesel yield of 93 wt.% within 1 h, and catalyzes the transesterification of waste soybean oil (acid value 5.1 mg KOH/g), achieving a yield exceeding 99 wt.% within 2 h^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
