The global market for biosurfactants is expected to reach USD 2‚308.8 million by 2020‚ according to a new study by Grand View Research‚ Inc. Escalating consumer preference towards the use of bio-based products‚ particularly in Europe and North America is expected to increase biosurfactant penetration. In addition‚ stringent regulatory policies are further expected to augment the biosurfactant demand over the next six years. Methyl Ester Sulfonate (MES) was the largest consumed biosurfactant‚ accounting

Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In

Introduction: This experiment focuses on carrying out a Perkin Reaction to synthesize (E) and (Z) isomers of α-phenylcinnamic acid. This was accomplished by refluxing benzaldehyde‚ phenylacetic acid‚ acetic anhydride and triethylamine as a base. The chemical equation of a Perkin Reaction can be seen below. The reaction mechanism for the synthesis of α-phenylcinnamic acid is shown below: Results: Theoretical Yield Therefore‚ phenylacetic acid is the limiting reagent. Table

Two distinctive reverberation types of benzene (top) consolidate to create a normal structure (base) In natural science‚ the term aromaticity is utilized to depict a cyclic (ring-molded)‚ planar (level) particle that shows strange dependability when contrasted with other geometric or connective game plans of the same arrangement of iotas.

A composite is defined as the combination of two or more chemically different materials that have properties better than when the compounds act alone. Resin composites‚ which are used in dentistry‚ are compounds composed of three separate agents that act together to form a rigid polymer. The three agents that act together to form the polymer include‚ an organic resin matrix‚ inorganic filler‚ and a coupling agent. The most important agent‚ the organic resin matrix‚ is typically composed of a compound

A VERIFICATION AND VALIDATION Verification and validation is a systems engineering discipline that determines if work products comply with their specifications and are fit for their intended use. More specifically: Verification establishes the truth of correspondence between a work product and its specification (from the Latin veritas‚ “truth”). Validation establishes the fitness of a software product for its operational mission (from the Latin valere‚ “to be worth”). It answers

by : Directorate of Education‚ Delhi SOME IMPORTANT REASONING BASED QUESTIONS OF ORGANIC CHEMISTRY 1. Chlorobenzene is less reactive than chloromethane. Ans. In chlorobenzene‚ each carbon atom of benzenering is sp2 hyridised and is electron withdrawing. Chlorine atom donates a lone pair of electron and acquire positive charge. The negative charge is delocalised on ortho and para position by resonance. C-Cl bond acquires partial double bond character and is 169 pm as compared to 17.0 pm in chloromethane

I started going to back to Phoenix with the intention of getting my MBA with an emphasis in IT Security. I then decided to just do an MBA and put of my “concentration” off to a later date‚ if ever. Like most people‚ there are many reasons to go back to school. Going further with my current job‚ possibly going on to a bigger and better job‚ and getting a feeling of self-satisfaction that I “did it” are the reasons I kept trying. This week we learned how to advance our positions in our individual
