styrene is desired for profit from the separation scheme. The first step in optimization is determining the order of separations from the reactor. All the possible chemicals present in the exiting stream are ethylbenzene, styrene, benzene, ethylene, toluene, methane, hydrogen, and water. Water is introduced as superheated steam to elevate reaction temperature and is an inert, driving the equilibrium reaction to the right, favoring styrene. Hydrogen will remain a gas at 65oC and 80 kPa (Reactor exiting

The results obtained from our calculations performed the core plug sample were desirable in that the values were ob effective porost conducted all equipment give us an appropriate means by which we could calculate the densities of the toluene, water, and oil, as well as calculating for oil, water, and gas saturations. One key thing about the lab is that it requires a lot of time and based on time consumption, we were not able to complete the lab the same day. The result of the experiment

Thin layer chromatography, or TLC, is used as a prerequisite for column chromatography. When performing types of chromatography, like TLC, the polarity of solvents is extremely important. This lab uses TLC plates, five solvents (hexane, toluene, ethyl acetate, dichloromethane, and acetone), and small evaporating dishes to determine which solvent would

principle, since the team observed the starting materials dissolved best in non-polar solvents, then the starting materials were non-polar themselves. Water was the most polar solvent, acetone was second, and toluene was third. The vegetable oil and olive oil dissolved completely in the toluene meaning they were very non-polar. The lard and shortening dissolved slightly, but dissolved better in the acetone. Therefore one can conclude that the lard and shortening is more polar than the oil, but not

scale. A dry polypropylene test tube was obtained and approximately 2 mL of p-xylene was squirted into it with the use of a pipette. This was added to the beaker and weighed. 10 drops of toluene was then added and weighed again. The polypropylene test tube, which now contained 10 mL of p-xylene and 10 drops toluene was removed from the beaker and placed into a replica 100 mL beaker which was halfway filled with an ice water mixture. The temperature sensor, which was connected to the microlab application

Phytochemical investigation of stem bark of Myrica esculenta Buch.-Ham. syn. M. nagi Hook.f. (Myricaceae) led to the isolation of four taraxerane-type triterpenoids characterized as 3β, 28, 30-trihydroxytaraxara-23-oic acid (1), 3β,28-dihydroxytaraxerane (2), 3β,30-dihydroxy- taraxerane-23-oic acid (3) and 3β, 12α, 28, 30-tetrahydroxytaraxeran-23-oic acid (4) which were elucidated using spectroscopic and chromatographic analysis. Keywords: Myrica esculenta, Myricaceae, pentacyclic triterpenoids

0 mL of 10% Na2CO3 was added to the distillate to neutralize acid. The funnel was swirled until there weren’t any pressure. The aqueous layer was drained from the funnel. The upper, cyclohexene, was poured to an Erlenmeyer flask. Next, 1.0 mL of toluene was added to the flask. The flask sat out for 5

Monomer and end capper was synthesized according to known literature procedures [10,11]. The conjugated polymer with two side-chain thiol groups was also synthesized by nickel mediated polymerization method [12,13]. A schematic representation of the synthesis of monomer, end capper, polymer was shown in Scheme 2. 2.2.1. 2,7-Dibromo-9H-fluorene (1) Fluorine (300.8 mmol, 50.0 g) and CHCl3 (450 mL) was taken in the 1 liter round-bottom flask, wrapped with aluminum foil. The solution was cooled to 0

and wrapped around a test tube until there was a fair amount. Even after the nylon was cut, it remained forming in the beaker and gave the resemblance of a sticky spider web. When checking the solubility of Nylon- 10,6 the three solutes- acetone, toluene, and ethanol-were placed in small Erlenmeyer flasks and following that, small pieces of the nylon were added. The nylon did not appear to be soluble in any of the three solutes. The last part of the experiment was the creation of slime. Slime is

Aromatic Compounds: Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain a ring of continuously overlapping p orbitals (planar). They have a delocalized pi electron in the ring. They are characterized by one or more planar rings of atoms joined by covalent bonds of two different kinds. The unique stability of these compounds is referred as Aromacity. Although aromatic has its origin from compounds characterized by its odor or fragrant, now, in chemistry, to
