Client Report 1 5/29/15 Clients: T.J. Maxx and Burlington Coat Factory Social Media and PR This week‚ I looked at the social media activity of T.J. Maxx and Burlington Coat Factory on Instagram‚ Twitter‚ and Facebook. In terms of Instagram‚ T.J. Maxx seemed to focus on spring fashions and trends this week. The pictures they used were sent to them by followers‚ whom they tagged and acknowledged in their posts. I thought this was a smart business strategy‚ because not only were they showcasing their

compound which contains acidic properties. An ester is an example of being a derivative of these organic acids. Esters can be prepared by the reaction of carboxylic acids and alcohols‚ with an inorganic acid used as a catalyst which is dubbed esterification. With o-hydrobenzoic acid‚ or salicylic acid‚ we are able to create acetylsalicylic acid otherwise known as aspirin as well as methyl salicylate‚ which is a component of oil of wintergreen. Both of which are used for pain relief/soreness. Salicylic

concentrate (C1)‚ however concentrate 1 did not create a visible spot on the TLC plate‚ so it is unclear whether or not carotenoids were present in concentrate 1. However‚ since concentrate 2 (C2) yielded 2 spots on the TLC plate‚ it is possible one of these spots was a carotenoid. In particular‚ spot 2 has the largest Rf value‚ indicating it was the least polar compound because it had the largest A value‚ traveling the farthest up the TLC plate with the non-polar developing solvent. It can be hypothesized

Stereochemistry of Dihydroxylation Reactions Question: Can the stereochemical outcome of dihydroxylation reactions be determined by thin layer chromatography? Overview: In this experiment‚ you will perform two reactions that transform alkenes into diols. While similar in functional group transformation‚ these reactions may lead to stereochemically different products. The two possible products are diastereomers of one another‚ and therefore have different physical chracteristics. After

fight certain cancers. In this lab you will isolate lycopene from tomato paste. To do this you will first extract carotenoid pigments from the paste and then use column chromatography to isolate the lycopene from the other pigments. You will then use TLC to evaluate the column chromatography separation. Note: because lycopene is light-sensitive‚ prevent any unnecessary exposure to light. Procedure: Weigh roughly 1.0 g of tomato paste into a 15 mL centrifuge tube. Add 4 mL of a 50/50 (% volume)

Preparation of an Acetic Acid Ester Abstract: 14.1 g of octyl acetate were synthesized from the esterification process using 20.0 ml of acetic acid and 17.9 g of n-octanol. The theoretical yield was 23.8 g of octyl acetate. The percent yield was 59.2%. The purification of the final ester was confirmed by boiling point (186-199°C) and infrared index (nD=1.419). It was a colorless liquid that had a slight fragrance of orange and indescribable chemicals. The Infrared spectra confirmed ester
