DAY 2:EKSU WINS IUPAC QUIZ, FIRST QUIZ OF THE SCSN NATIONAL ANNUAL CONFERENCE

Today, on the 24th of September 2019, the day 2 of the Students chemical society of Nigeria annual conference 2019 hosted by KOGI STATE UNIVERSITY, Ekiti State University came first at the IUPAC QUIZ.

 Representing the school was Akinbola Afeez Akintunde from department of industrial chemistry Ekiti State University.

 The quiz was based on periodic table.
Each students were asked to provide 10 words, all comprising of The elements in the periodic table.

  After which series of questions were thrown before the winner finally emerged.

Lectures were also given by guest speakers and students.

Below are the lectures given:

CARBON DIOXIDE: A RAW MATERIAL FOR THE SYNTHESIS OF USEFUL ORGANIC SUBSTANCE -

A Seminar Paper

PRESENTED AT THE 17TH NATIONAL CONFERENCE OF THE STUDENTS CHEMICAL SOCIETY OF NIGERIA (SCSN) HELD AT KOGI STATE UNIVERSITY

  By  ISHAQ Abdulbasir 24th Sept. , 2019.    

Carbon dioxide is a favorable C1 feedstock due to its abundance, availability and low toxicity, To avoid the obvious consequences on climate change, the concentration of this greenhouse gas in the atmosphere must be stabilized.
Since the beginning of the industrial revolution and the concomitant use of fossil resources, the concentration of carbon dioxide significantly increased in the atmosphere[1].

This seminar paper will give an account on the readily available and feasible ways of capturing CO2 from the atmosphere and how they can be converted to useful organic compound

Direct Air Capture of CO2 with Chemicals.

 Direct air capture” (DAC) involves a system with an “air contactor” where ambient air flows over a chemical sorbent that selectively removes the CO2 [1].

Ureas

Ureas Carboxylic acids Alcohols Lactones Cyclic carbonates Some Useful Organic Compound Synthesis from CO2

Ureas are a class of organic compounds with the formula (R2N)2CO.
Ureas are an important class of bioactive organic compounds in organic chemistry and exist widely in natural products, agricultural pesticides, uron herbicides, pharmaceuticals, organic fertilizer [2].

Synthesis of Urea from CO2 Transformation of CO2 to urea through treatment with amines

 [3] Synthesis of Carboxylic Acids from CO2 The most straight forward method for accessing carboxylic acids is the direct carboxylation of carbon nucleophiles using CO2 [4].

A good example is cooperative iron–copper catalyzed hydrocarboxylation of terminal alkene. X. Wu, & F. Zheng, Top Curr Chem (Z), 2017, 375:

Cyclic carbonates These are organic carbonate, that consist of a carbonyl group flanked by two alkoxy groups. The carbonate groups are linked by a 2 or 3 carbon bridge, forming a cyclic compounds. They are use as precursor for the preparation of other organic compounds, monomers for polymer synthesis, industrial lubricants. Synthesis of Cyclic Carbonate from co2 Conversion of epoxides with CO2 in the presence of bifunctional ammonium salt

Synthesis of Lactone from CO2This involve the coupling of CO2 with unsaturated diene or dinye in the presence of a metal catalyst.

Conclusion
In conclusion, the preparative aspects of using CO2 in the synthesis of useful organic compounds undoubtedly represent a key strategy for the development of greener chemical processes. The challenge, therefore, is to achieve CO2 transformations from natural and industrial sources, as well as human activities.
