What is Organic Chemistry ?

Organic chemistry is a branch of chemistry which involve the scientific study of structure, properties & reactions of organic species, compounds or organic materials, means matter have various forms found that contains carbon atoms. Study of structure of organic chemistry compounds includes use of spectroscopy techniques like IR Spectroscopy, Microwave Spectroscopy, NMR Spectroscopy, Mass Spectroscopy, X – Ray Diffraction, Electron Diffraction, Neutron Diffraction and other physical and/or chemical type of methods to examine chemical composition and chemical constitution of the organic chemistry compounds and materials to be analysed. This is article on what is organic chemistry at “chemistry notes info blog”. Study of properties of organic compound includes study of both physical properties as well as chemical properties of organic chemistry compounds, which uses the similar methods and also methods to evaluate the chemical reactivity to understand behaviour of organic matter (organic sample) in its pure form (if when possible), otherwise in solution, mixture forms. Study of chemistry of organic reactions includes the searching their possibility through use in the preparations of goal molecule or compounds like natural products, medicinal drugs, polymers, solvents, etc.) by their chemical synthesis, also focused on the study of  reactivity’s of the individual organic molecules. This article is about basics understanding of organic chemistry under post organic chemistry lecture notes at . Below is a 3D diagram of methane CH4 molecule in tetrahedral geometry with bond angle of 109 degree.

 To identify purity of organic compounds methods or techniques used now-days are Chromatography like HPLC (High Performance Liquid Chromatography), GC (Gas Chromatography) and Spectroscopy like Nuclear magnetic resonance (NMR) spectroscopy, Mass spectrometry, Crystallography. and old methods and techniques to identify purity of organic compounds are distillation, crystallization, and solvent extraction.

Physical Properties of Organic Compounds

These properties help in both qualitative and quantitative manner. Quantitative info includes M.P. (melting point), B.P. (boiling point), & index of refraction. Qualitative info includes odor, solubility, consistency and color.

Nomenclature in Organic Chemistry

Organic compounds are generally named in two ways i.e. traditional names and systematic names. Traditional names are parent names like for Vitamin B3, its traditional name is Niacin. Systematic names are scientific names given by IUPAC (International Union of Pure and Applied Chemistry) nomenclature system like for Vitamin B3, its systematic name by IUPAC system is Pyridin-3-Carboxylic-Acid.

Classification of Organic Compounds

Organic compounds are classified on the basis of Functional Groups, Aliphatic compounds, Aromatic compounds, Heterocyclic compounds, Polymers, Biomolecules etc.

Organic Reactions

Organic reactions are those chemical reactions which involve organic compounds.

Extraction of Essential Oil by Steam Distillation of Tulsi (Ocimum Basillicum)

Extraction of Essential Oil by Steam Distillation of Tulsi (Ocimum Basillicum)

Essential oils are insoluble in water and evaporate easily. We can obtain essential oil from plant tissues by distillation or extraction processes. Generally essential oils are obtain from every part of plant like stem, root, leaves, flowers, seed, branches etc. And these essential oils are used in the preparation of drugs, cosmetics and perfumes.
Holi Tulsi Plant
Ocimum Basillicum means Tulsi is an aromatic plant. Ocimum Basillicum is used to obtain essential oil useful for different application. This oil evaporates within 24 hours after applying it to our body. This essential oil helps in cure of digestion problem, strained muscles, headaches and nervous breakdowns. Due to its good medicinal properties and aroma its demand is very high in many countries. A person or company can build a small or large scale industry for the extraction of essential oil from Ocimum Basillicum (Tulsi).

Top 10 General qualitative properties of Ocimum Basillicum essential oil are given below-

essential oil extraction equipment photo1.  Appearance : Transparent fluid
2.  Color : Pale yellow
3.  Fragrance : Ocimum Basillicum’s distinctive flavor and fragrance
4.  Refractive Index on 20°C : 1.51200 to1.51900
5.  Specific Gravity on 25°C : 0.95200 to 0.97300
6.  Optical gyration on 25°C : [-] 8.85º to [-] 11.85º
7.  Well mixed with Hydroxycitronellal
8.  Insoluble in water
9.  Dissolved in paraffin oil

How to obtain oil from holi Tulsi plant?

The extraction of essential oil by steam distillation of ocimum basillicum (Tulsi) is a solid-liquid extraction process. This process completes in following steps-
Flow diagram of steam distilatillation
1.  Collect plant material and dry it if required.
2.  Fill this plant material in distillation vessel.
3.  Add water or solvent (like Ethanol, n-Hexane) in distillation vessel.
4.  Heat the mixture in well-equipped distillation vessel in control environment and controlled temperature, then
5.  Diffusion of essential oil from inside of solid material of plant to its surface occurs, then
6.  Transfer of mass from surface of plant solid material to surrounding liquid occurs, then
7.  This liquid contains essential oil which is obtained by reverse cooler.
8.  Then the collection of above liquid obtained from reverse cooler is put to stand for some time then essential oil come over water, then
9.  We perform layer separation to separate out essential oil from water, then
10.              Store this essential oil in dark, closed vessel for future use.
how to obtain Essential oil by steam distillation ?
The experimental results proves that yield of essential oil of Tulsi (Ocimum-Basillicum)  from only leaves of plant is slightly higher than from the mixture of leaves and stems (means plant crush).
