The thermometer is first dipped in the sulphuric acid, and then the drop of acid which clings to the bulb is smeared on the side of the capillary tube containing the substance. The capillary tube is then made to adhere to the thermometer (Fig. 6) by capillary attraction, so that the substance in the tube is just opposite the bulb of the thermometer. This method is much better than using a rubber band, which is apt to perish in the sulphuric acid fumes, and gives rise generally to a speedy discoloration of the acid. [Pg.18]

In the synthesis (Expt 8.34), formylacetic acid is formed in situ by the action of a concentrated sulphuric acid-fuming sulphuric acid mixture on malic acid (H02OCH0H CH2 C02H). This a-hydroxydicarboxylic acid undergoes decarbonylation and dehydration under these conditions before the acid-catalysed self-condensation of formylacetic acid. The cyclisation step is generally applicable to / -keto esters. [Pg.1173]

Experiment 126. — Put three or four crystals of potassium iodide in a test tube and add a few drops of concentrated sulphuric acid. Fumes of hydriodic acid are formed among other products. Observe the most obvious properties of these fumes as in Exp. 120, and compare with the fumes of hydrochloric and hydrobromic acids. Are the acids similar ... [Pg.254]
