Preparation Of Triphenylmethanol Objectives 1. To study the preparation of triphenylmethanol using through Gridnard reaction 2. To study the operations of anhydrous reaction‚ water vapor distillation. Principles Alcohol is widely used in organic chemistry‚ not only as solute but also as intermediate to synthesize halide‚ alkene‚ ether‚ aldehyde and ketone etc. In laboratory‚ an important method of synthesizing alcohol is though the addition reaction of Gridnard reagent and carbonyl compound‚ whereas

Abstract: The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product. The mixture was then mixed with sulfuric acid and the organic layer was extracted via a separatory funnel. The mixture was then recrystallized from methanol and was allowed

Grignard Synthesis of Triphenylmethanol Aim The aim of this experiment was to prepared Grignard reagent (phenylmagnesium bromide) from bromobenzene and magnesium‚ to use the reagent prepared to synthesise a tertiary alcohol (triphenylmethanol) by reacting reagent and ester (methyl benzoate)‚ and the product formed is analyse by infrared spectroscopy (IR)‚ melting point‚ thin layer chromatography (TLC)‚ gas chromatography mass spectrum (GCMS) and finally Nuclear Magnetic Resonance spectroscopy.

Grignard Reaction: Synthesis of Triphenylmethanol Dominic DiRaimo Lab Partners: Roxana Hernandez Somata Thach TA: Sreya Mukherjee December 5‚ 2013 Introduction Grignard reagents are good nucleophiles as well as strong bases (Weldegirma). It allows compounds to react with acidic compounds‚ therefor is must be free from acids as well as water during the desired reaction. Another important aspect of Grignard reagent is that refluxing is necessary to

Running head: TRANSFORMATION AT THE IRS Module 8: Transformation at the IRS AMP 492 September 25‚ 2011 Introduction The purpose of this paper is to discuss the transformation at the IRS by examining the need for change‚ the outcome of change and the process of change. The challenges faced by the IRS will be discussed and Kotter’s 8-step model will be applied to the case study to determine whether or not it was or could have been implemented more effectively. This paper will provide an opinion

Megan Wierzbowski Organic II Laboratory Wed. 11-1:50 Title: Grignard Reaction with a Ketone: Triphenylmethanol Part 1 Objective: The goal of this experiment is to learn to make Grignard reagents. The reactions of the Grignard reagents with ketones form tertiary alcohols. These reagents are highly air- and moisture-sensitive materials. We will observe the formation of the Grignard reagents‚ which magnesium metal is transformed into organometallic salts. Experimental Procedure:

We began the negotiation process with very optimistic outcomes in mind‚ whilst considering our fall back options which would exceed current employer/ competitor offerings and protect the long term interests of the employees. We as the employee/ union group believed that the

The Grignard Synthesis of Triphenylmethanol Organic Chemistry Lab II March 19‚ 2012 Abstract The purpose of this experiment was to synthesize the Grignard reagent‚ phenyl magnesium bromide‚ and then use the manufactured Grignard reagent to synthesize the alcohol‚ triphenylmethanol‚ by reacting with benzophenone and protonation by H3O+. The triphenylmethanol was purified by recrystallization. The melting point‚ Infrared Spectroscopy‚ 13C NMR‚ and 1H NMR were used to characterize and confirm

When you receive an IRS audit‚ it can be a scary event and it is difficult to find out what you should do next. For anybody who is not really an expert on taxes and audits‚ most of the tax terminology seems like it could be another language. Many people are unsure about how to safely proceed when they were selected for an IRS review. Should you simply go through the motions alone or do you require expert help? How can you properly evaluate your tax filings? Several such questions come up in your

deliberates the comparison and contrast on the key features of Human Resource Management and Industrial Relations in academic fields. Definitions of terms HRM and IR will be identified through the review of the origin and development of these two areas. Moreover‚ I have pointed out the theoretical scope of the two subjects and key features of HRM and IR. Finally‚ there is comparison and contrast between given subjects through the historical retrospective and paper review. Definition of Industrial Relations
