Magnesium carbonate light

For electrical insulation china clay is commonly employed whilst various calcium carbonates (whiting, ground limestone, precipitated calcium carbonate, and coated calcium carbonate) are used for general purpose work. Also occasionally employed are talc, light magnesium carbonate, barytes (barium sulphate) and the silicas and silicates. For flooring applications asbestos has been an important filler. The effect of fillers on some properties of plasticised PVC are shown in Figure 12.21 (a-d). [Pg.338]

The serum unsaturated iron binding capacity and total iron binding capacity (TIBC) are determined by addition of sufficient Fe to saturate iron binding sites on transferrin. The excess Fe " is removed (e.g., by adsorption with light magnesium carbonate [MgCOs] powder), and the assay for iron content is then repeated. From this second measure-... [Pg.1189]

If pivaloyl chloride is used, the amine or its hydrochloride (up to 5 mg) is suspended in chloroform (200 /il) and light magnesium carbonate (50 mg) is added. To the stirred suspension is added a 110% molar excess of pivaloyl chloride via a microlitre syringe, and the reaction is allowed to proceed at room temperature for 30 minutes. After centrifugation, the supernatant is evaporated to dryness in a stream of nitrogen or in vacuo, and the residue is dissolved in a suitable solvent for analysis by TLC or GC [138]. [Pg.46]
