Separation and Purification of Organic Compounds

Abstract The distillation process was successfully done because of the separation of water from the acetone. When the distillate was lighted with the matchstick it produced flame which indicates that there was more presence of acetone than water. When the sodium nitroprusside, sodium hydroxide and glacial acetic acid was added to the distillate, it turned to violet. This means that there is the presence of ketone. Introduction Distillation is the process heating a liquid until it boils, then condensing and…...

Extraction and Evaporation Recrystallization

1. To the components of a simulated pharmaceutical preparation, Panacetin, and identifying the unknown component of the mixture through extraction and separation methods. 2. To learn how to purify by recrystallization, how to dry them and how to obtain a melting point. PRECAUTION: ACETANILIDE AND PHENACETIN ARE EYE AND SKIN IRRITANTS. Minimize contact with your unknown compound. THEORY: In this experiment, Panacetin, a pharmaceutical preparation will be separated from its components by making use of their solubilities and acid-base properties.…...

Evaporationin Our Daily Life

In a society based only on materialistic possessions, sometimes we overlook even the simplest of things, and the most valuable to our survival as a human race and as a planet. Everywhere around us people envy great architects and artists because of their remarkable creations. Though, we, as a human race disregard the importance of less tangible commodities, developed by the greatest artist ever, Mother Nature. She has given us the most magnificent and staggering artwork imaginable, our environment. But…...

Steam Distillation

Introduction The purpose of this experiment is to extract Eugenol from Cloves using steam distillation as a purification technique and to transfer Eugenol from the aqueous phase to the MeCl2 phase. With steam distillation, the boiling point of a mixture of immiscible liquids is lower than the boiling points of the individual components. Water from the steam is one of the components of an immiscible liquid mixture. The vapor pressures of each of the components during the distillation are additive.…...

The Process of Water Evaporation

Transpiration is the evaporation of water from plants. It’s not simply a hazard of plant life but it’s the engine that pulls water from the roots to cool the leaf and supply photosynthesis. The concentration of water vapor in the atmosphere is lower than that in the leaf. Because of this difference, water vapor diffuses from the spaces of the leaf, through the stomata in the epidermis. Stomata are in the lower epidermis; the lower surface receives less radiation from…...

The Water Cycle

Nutrients are elements essential for life on Earth. The most important of these nutrients are water, carbon (and oxygen), nitrogen, and phosphorous. These nutrients are recycled throughout the ecosystems to provide for the living organisms. Water takes up more than two-thirds of the Earth’s surface and makes up almost 70 percent of living matter (Pidwirny, 2006). Such abundance of water on Earth makes it also the most valuable among the nutrients. Water cycle recycles water with the use of processes…...

Linear Shrinkage Test

AIM: To determine the linear shrinkage likely to be experienced by clay material THEORY: Linear shrinkage is the decrease in length of a soil sample when oven-dried, starting with a moisture content of the sample at the liquid limit. This test is used to measure the percentage decrease in dimension of a fine fraction of a soil when it is dried after having been moulded in a wet condition approximately at its liquid limit. The linear shrinkage is found by…...
