of hairspray. Industrial suppliers can increase their net profit of aerosol hairspray production by analyzing and possibly optimizing their manufacturing process, mores specifically, the production of the most widely used aerosol propellant, dimethyl ether (DME). The optimization of a thermally coupled DME reactor (OTCDR) proves to be economical, energy sufficient, and increase the net profit of the industrial plant. It is in the best interest of industrial aerosol hairspray manufacturers to consider

substances dimethyl ether and propane have both similarities and differences. Both of these molecules two carbon atoms that have tetrahedral molecular geometry. The dimethyl ether’s third atom, hydroxide, has bent molecular geometry, while propane’s third atom, carbon, has tetrahedral molecular geometry. Both of the molecules have three central atoms. The propane molecule only contains carbon and hydrogen atoms, which makes the line structure not have any element symbols. The dimethyl ether molecule

A 1,3,4-thiadiazole library was constructed by solid-phase organic synthesis. The key step of this solid-phase synthesis involves the preparation of polymer-bound 2-amido-5-amino-1,3,4-thiadiazole resin by the cyclization of thiosemicarbazide resin using p-TsCl as the desulfurative agent, followed by the functionalization of resin by alkylation, acylation, alkylation/acylation, and Suzuki coupling reaction. Both the alkylation and acylation reactions chemoselectively occurred at the 2-amide position

Chapter Five Discussion Extraction is a process by which substances and active constituents are separated from the original matrix, extraction process depends on many physical and chemical characteristics. Extraction is divided into two types liquid phase extraction and solid phase extraction depending on the physical phase of extraction agent(Rezaee et al., 2006). In our study, we have adopted liquid phase extraction for several reasons. Firstly, simple, inexpensive, relatively precise and wide

Conclusion: The isomerization of dimethyl maleate to dimethyl fumarate experiment was successful in that it occurred to completion under the correct conditions. Only the predicted set of conditions allowed for isomerization of dimethyl maleate to dimethyl fumarate, a test tube of dimethyl maleate and bromine placed under an intense light source. The other two test tubes did not isomerize as one did not contain the bromine, so there was no ability to form a radical, and the other was placed in the

PRODUCTION OF PET We utilize the rapidity of ester-interchange reactions during the production process. The acid (terephthalic acid) is converted to the dimethyl ester, which is further purified by distillation or crystallization. This is then allowed to react with the glycol by ester interchange. The reaction generally is a two-step reaction a. First, low MW polyester is made with excess of glycol to ensure that the hydroxyl end groups are formed and then the temperature is raised and pressure is

Korleyfah Mouth Chem 331 Thursday 2:00pm Dr. Lijuan Li 20A Preparation of CuCl2~2DMSO 20B Preparation of RuCl2~4DMSO Abstract In order to synthesize our metal complexes, we were able to make both Copper and Ruthenium metals. From this, we combined each metal complex with DMSO by refluxing the compound. The metal complexes were analyzed through their melting point and IR spectroscopy to determine whether the metal bonded to a Sulfur atom or an Oxygen atom of the DMSO. After analyzing the IR spectrum

Throughout the many decades that America has been in existence there have been many interesting mysteries that have not been solved and myths passed down from generation to generation. No one knows what caused these myths to come about or why these mysteries were never solved, but they are a very interesting part of American history. From mysteries involving serial killers to myths about mysterious creatures, there is a wide range of the unknown that many people, except for witnesses, have never

RESEARCH “Magic Mud” is mainly a mixture of a dusty substance known as “Cornstarch”, and a liquid known as “Tonic Water”. When you apply pressure to the substance of Magic Mud, it will act as if it were a solid. Once you stop applying pressure to it, the substance will act as if it were a liquid. To make this happen you should apparently mix tonic water and cornstarch for a long period of time to allow this chemical reaction to occur. What I wanted to know is if this would still be possible if
