    the world and sometimes different bodies have different views on food color safety. In the United States‚ FD&C numbers (which indicate that the FDA has approved the colorant for use in foods‚ drugs and cosmetics) are given to approved synthetic food dyes that do not exist in nature‚ while in the European Union‚ E numbers are used for all additives‚ both synthetic and natural‚ that are approved in food applications. The food colors are known by E numbers that begin with a 1‚ such as E100 (turmeric)

    eugenol in the basic aqueous layer‚ and acetyleugenol in the organic layer. The basic aqueous layer can be acidified to re-extract eugenol from it. And the organic layer can be dried and concentrated to yield acetyleugenol The principle of steam distillation is based on the fact that two immiscible liquids will boil at a lower temperature than the boiling points of either pure component‚ because the total vapor pressure of the heterogeneous mixture is simply the sum of the vapor pressures of the individual

    The earliest surviving examples of pre-Colombian tie-dye in Peru date from 500 to 800A.D. Their designs include small circles and lines‚ with bright colors including red‚ yellow‚ blue‚ and green.[4] Shibori includes a form of tie-dye that originated in Japan. It has been practiced there since at least the eighth century. Shibori includes a number of labor-intensive resist techniques including stitching elaborate patterns and tightly gathering the stitching before dyeing‚ forming intricate designs

    Title: Distillation of an Ethanol Using Fractional Distillation Lab Report Abstract: This experiment aimed to separate the components of a mixture using Fractional Distillation. A volume of 28.0mL of a mixture including ethanol was heated until the temperature reached 78.0 C. Approximately 1.0mL of distillate was collected between 78.0 – 84.0 C. Percent composition by weight of the 1.0mL sample was determined to be 95% ethanol. By careful and accurate techniques‚ a high percent composition

    Cheryl Baclit Chem 234 Experiment 4: 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

    Natural dyes Natural dyes are dyes or colorants derived from plants‚ invertebrates‚ or minerals. The majority of natural dyes are vegetable dyes from plant sources – roots‚ berries‚bark‚ leaves‚ and wood — and other organic sources such as fungi and lichens. Archaeologists have found evidence of textile dyeing dating back to the Neolithicperiod. In China‚ dyeing with plants‚ barks and insects has been traced back more than 5‚000 years.[1] The essential process of dyeing changed little over time
