Molisch s test A general test for carbohydrates. The carbohydrate is dissolved in water, alcoholic 1-naphthol added, and concentrated sulphuric acid poured down the side of the tube. A deep violet ring is formed at the junction of the liquids. A modification, the rapid furfural test , is used to distinguish between glucose and fructose. A mixture of the sugar, 1-naphthol, and concentrated hydrochloric acid is boiled. With fructose and saccharides containing fructose a violet colour is produced immediately the solution boils. With glucose the appearance of the colour is slower. 

It is useful to measure the melting point of the solid resins. This can be done either by the ring and ball technique or by Durrans mercury method. In the latter method a known weight of resin is melted in a test tube of fixed dimensions. The resin is then cooled and it solidifies. A known weight of clean mercury is then poured on to the top of the resin and the whole assembly heated, at a fixed rate, until the resin melts and the mercury runs through the resin. The temperature at which this occurs is taken as the melting point. 

Bent discusses how the sulphur melts to form a fluid liquid, which then becomes quite viscous before being poured into cold water we imagine the breaking of Ss rings, polymerisation of small chains and then quenching of the polymeric chains without re-formation of Ss rings for some time. 

The cyclohexene (ring C) can be disconnected by a Diels-Alder reaction to reveal enone (32) and diene (33). Pour chiral centres remain in (32) so three are Introduced in the Diels-Alder reaction. 

Muratic acid is powerful. Thick gloves were worn along with eye protection. Using a stainless steel teaspoon, about 1-5ml (1 teaspoon) of muratic acid was poured into a pickle jar that contained roughly 3/4 filtered water (15 ounces or about 500ml.) The pickle jar was previously washed twice in a dishwasher in an attempt to ensure sterility. Under the lid of the pickle jar the manufacturer had painted on a thin ring of some type of latex or rubber to help seal the jar. The mixture of water and acid do not seem to affect the ring (it doesn t dissolve or melt the latex in any way) so the jar and its lid were used. 

Free the plug of debris from the sides of the tube by ringing the tube with an applicator stick, and carefully pour the top three layers into a discard container. With the tube still tipped, use a swab to remove debris from the sides of the tube. This step is very important, for lipid droplets which reach the sediment make examination difficult. 

The usual form of sulfur is known as the rhombic form, which is stable at temperatures up to about 105 °C. Above that temperature, the monoclinic structure is stable. A plastic form of sulfur can be obtained by pouring liquid sulfur into water to cool it quickly, but on standing it is converted to the rhombic form. On a molecular level, the element exists as S8 rings that have the structure... 

Set up the test tube, ring stand, and utility clamp. Obtain about 3 mL yeast suspension in a 10-mL graduated cylinder, and pour it into the test tube. Obtain about 3 mL 5% sucrose solution in a 10-mL graduated cylinder. Add the sucrose solution to the yeast in the test tube. Stir to mix. Pour enough vegetable oil on top of the mixture to completely cover the surface. 

The color solution was poured into a 100 mL separatory funnel supported on a ring support. Ten milliliters of n-butyl alcohol was added and shaked gently until the color is transferred to the upper layer. The lower layer was drawn off and discarded. The extraction procedure was repeated two times with 5 mL n- butyl... 

The SEXAFS teehnique is a partieular surface sensitive detection mode applied to an EXAFS measurement, performed in a particular environment, the Ultra High Vacuum, which is needed in order to prepare and protect the atomic-scale eleanliness of surface and interface systems for the whole time length of the experiment. As such the technique borrows equipment and procedures from the surface science spectroscopies, and exploitation procedures of the synchrotron radiation source from the conventional, non vacuum, EXAFS method. The studies described below have been performed at the Laboratoire pour T Utilisation du Rayonnement Electro-magnetique (LURE) exploiting synehrotron radiation from the storage ring DCI...
