Luting

Red lead is a useful ingredient of anti-rusting paints, in which it is mixed with linseed oil. If glycerol is added to this mixture, a cement suitable for luting (i.e. making airtight or watertight) joints in iron pipes or vessels is obtained. 

This difference in behavior for acetic acid in pure water versus water buffered at pH = 7 0 has some important practical consequences Biochemists usually do not talk about acetic acid (or lactic acid or salicylic acid etc) They talk about acetate (and lac tate and salicylate) Why Its because biochemists are concerned with carboxylic acids as they exist in di lute aqueous solution at what is called biological pH Biological fluids are naturally buffered The pH of blood for example is maintained at 7 2 and at this pH carboxylic acids are almost entirely converted to their carboxylate anions...

Graphite is frequently, although incorrectly, analyzed by the proximate method used for coal in which the volatile material is deterrnined by strongly beating the sample in a covered or luted cmcible. Some oxidation of the graphite always occurs so that the value obtained for volatile matter is high and thus the "fixed carbon" is too low. The method lacks both accuracy and precision.

The correct way to light a furnace (hot or cold) that bums gas or burns light oil is to start with a positive isolation, such as a slip-plate, in the fuel line. Other positive isolations are disconnected hoses, lutes filled with water (if the fuel is gas at low pressure), and double block and bleed valves closed valves without a bleed are not sufficient. Then ... 

These compounds showed a remarkable activity toward Gram-positive (e.g.. Bacillus cereus, Staphylococcus aureus, Sarcina luted) and Gram-negative bacteria (e.g.. Pseudomonas sp.) the activity was somewhat lower in the styryl derivatives (82MI2).
