INTRODUCTION

Calcium Gluconate is the calcium salt of gluconic acid, an oxidation product of glucose, and contains 9.3% calcium, which is about one-third of the calcium in the strength of calcium chloride. It is an ingredient found in a variety of supplements and vitamins and is used to lower potassium in the blood. Calcium gluconate is used as a mineral supplement and medication when there is insufficient calcium in the diet. Supplementation may be done to treat or prevent osteoporosis or rickets, consequences of hypocalcemia.

Manufacture
It is made by mixing gluconic acid with calcium carbonate or calcium hydroxide

5-Methyl-3-vinyl-2-oxazolidinone (V-MOX) is a highly reactive monomer valued for its low viscosity, mild odor, and excellent reactivity. It is widely used as a reactive diluent in UV-curable inks and coatings, where it enhances adhesion, produces brighter colors, and improves safety compared to conventional diluents. In addition, V-MOX serves as a key building block in the synthesis of kinetic hydrate inhibitor (KHI) polymers, which are applied in oil and gas production to prevent hydrate blockages in pipelines.
