Emulsion

liquid as possible. Let the solution cool to room temperature. 3. Pour the tea into the separatory funnel. (Make sure that the stopcock is closed). Add about 10 to 20 ml of methylene chloride and shake gently. Vigorous shaking will lead to an emulsion.…

without altering the polymerization rate by using chain transfer agents. However, large increases in molecular weight can only be made by decreasing the polymerization rate, by lowering the initiator concentration or lowering the reaction temperature. Emulsion polymerization is a unique process in that it affords a means of increasing the polymer molecular weight without decreasing the polymerization rate. The difficulty of removing all impurities such as surfactant residues from the polymer is…

However, improvements for this experiment may be to use a higher percentage of sodium bicarbonate to get rid of emulsions and hydrochloric acid, as well as use a water bath to speed up the evaporation time. Another improvement may be to use alumina as a filtering agent to get rid of the additional byproducts. Friedel-Crafts acylation occurs as a quality control assay…

The Renaissance was a big explosion of the arts, science, social, and political thoughts in Europe after the Middle Ages. After The Black Plague, Europe lost half or more of its population the market went down. With less people living the less costumers there was for any type of trade but then the population suddenly got higher than it ever was before and more trades and marketplaces, more discovery of science and more art going around and thus was born the Renaissance! Some of the most famous…

Airway/Pain Management Mentor Experience Reflection Mentoring is the most valued factor in an educational setting. The performance of the group depends on the competency of the mentor. Confidentially, professional skill and communication are the three most important characteristics of an instructor pose to have an active mentorship (Dunn, 2012). Professional competency of the mentor is one of the principal mentor characters leads the mentee towards professional skill development. In the…

plate in photography was the next advancement. This is when a glass plate is coated with a gelatin emulsion of silver bromide where a picture could be imprinted on. It was able to be mass produced adding to its benefits. This idea came from R.L. Maddox. This idea was morphed into the celluloid film base idea. This is a transparent substrate that behaves like a support medium for the photosensitive emulsion projected onto it. This was the first time a roll of film could be easily used in a…

RECENT TRENDS ON PURIFICATION OF SEA WATER INTRODUCTION SEAWATER: -Sea water or salt water is water from sea or ocean. Sea or ocean water accounts for the most percentage of water on the earth. Almost anything can be found in sea water. This includes dissolved salts from earth’s crust and material released by micro organisms. It is the most impure form of natural water. Rivers join sea and throw in the impurities carried by them. Moreover continuous evaporation of water from the surface of sea…

vacation to Santo Domingo in 1877. George never made the trip, but consequently this sparked his interest in photography. “ He would toil at the bank all day, six days a week, then spend his evenings… experimenting tirelessly with various photo emulsions” (Zinsmeister). This accidental discovery of an interest led him to revolutionize the photographic world. George Eastman’s developments and invention in the photographic process, along with his many contributions to educational foundations lead…

volatile and non-volatile elements is separated through the steam distillation method with temperature being below 100 oC. Moreover, the method is used to extract essential oils. The cinnamaldehyde will be conveyed up with the distillate, observed as an emulsion on the condensed vapor. It will turn milky on cooling. Methylene chloride will be sued to obtain it from the distillate. It will then be evaporated leaving behind the pure compound. Reactions: Cinnamaldehyde Chemical Formula: C9H8O…
