CYCLOPROPANE

 Cyclopropane (CAS No.:75-19-4) was discovered in 1881 by August Freund, who also proposed the right structure for the new substance in his first paper. Freund reacted 1,3-dibromopropane with sodium, the reaction is an intramolecular Wurtz reaction leading directly to cyclopropane.The yield of the reaction can be improved by the use of zinc instead of sodium.Cyclopropane had no commercial application until Henderson and Lucas discovered its anaesthetic properties in 1929 ; industrial production had begun by 1936.

DOT Classification:  2.1; Label: Flammable Gas

The Cyclopropane is an organic compound with the formula C₃H₆. The IUPAC name of this chemical is cyclopropane. With the CAS registry number 75-19-4, it is also named as Cyclopropan. The product's categories are Organics; Chemical Synthesis; Compressed and Liquefied Gases; Synthetic Reagents. Besides, it should be stored in a closed and dry place.

The Cyclopropane is an anaesthetic when inhaled. In modern anaesthetic practice, it has been superseded by other agents, due to its extreme reactivity under normal conditions: when the gas is mixed with oxygen there is a significant risk of explosion.

Physical properties about Cyclopropane are: (1)ACD/LogP: 1.58; (2)ACD/LogD (pH 5.5): 1.581; (3)ACD/LogD (pH 7.4): 1.581; (4)ACD/BCF (pH 5.5): 9.371; (5)ACD/BCF (pH 7.4): 9.371; (6)ACD/KOC (pH 5.5): 172.668; (7)ACD/KOC (pH 7.4): 172.668; (8)Index of Refraction: 1.433; (9)Molar Refractivity: 13.835 cm³; (10)Molar Volume: 53.24 cm³; (11)Polarizability: 5.485×10^-24cm³; (12)Surface Tension: 25.926 dyne/cm; (13)Density: 0.79 g/cm³; (14)Enthalpy of Vaporization: 20.05 kJ/mol; (15)Vapour Pressure: 5348.461 mmHg at 25°C.

Preparation: this chemical can be prepared by 1,3-dibromo-propane. This reaction will need reagent zinc dust. The reaction temperature is 200 - 300 °C. The yield is about 78%.

Uses of Cyclopropane: it can be used to produce 1,3-dichloro-propane, 3-chloro-propene, chloro-cyclopropane, 1,1-dichloro-cyclopropane at temperature of 600 °C. It will need reagent Cl₂, SiF₄. The yield is about 83.5%.
