Crystal Pesticide Intermediates Ferrocene Organo - Transition Metal Compound

Intermediates of Pesticide ferrocene organo-transition metal compound

Ferrocene is a kind of organic transition metal compound with aromatic nature. It is also called as dicyclopentadienyl iron. It contains a divalent iron cation and two cyclopentadienyl anions in its molecular structure. It is also the raw materials for production of ferrocenecarboxylic acid.

In 1950s of the last century, people had first successfully produced it with the reaction between cyclopentadienyl magnesium bromide and anhydrous ferric chloride. At room temperature, it is orange needle crystal powder with a similar smell as camphor and belongs to non-polar compound.

It is soluble in many organic solvents such as methanol, ethanol, ethyl ether, petroleum ether, gasoline, kerosene, diesel oil, methylene chloride, benzene, toluene, and xylene, Because of the large polarity of ethanol polarity, it is usually recommended to dissolve it with toluene. It is insoluble in water but soluble in concentrated sulfuric acid. It is also insoluble and doesn’t decompose in boiling caustic soda solution and hydrochloric acid.

It molecule exhibits polarity with higher thermal stability, chemical stability and radiation resistance. It has wide range of application in industry, agriculture, medicine, aerospace, energy, environmental protection and other industries. Main applications are described below:

(1)It can be used as the fuel saving smoke suppressants and anti-knock agent. For example, it can be used for the production of gasoline antiknock agent, the fuel catalyst of rocket propellant and also the solid fuels of aerospace.

(2) It can be used as the catalyst such as catalyst for the production of ammonia, as the curing agent of silicone rubber; it can prevent the degradation of polyethylene by light; when applied to agricultural mulch, it can break its natural degradation without affecting the cultivation and fertilization within a certain time.

(3) It can be used as a gasoline anti-knock agent. It can substitute gasoline toxic tetraethyl lead for being used as the anti-knock agent and for production of high-grade unleaded petrol in order to eliminate the contamination of the environment and poisoning to human body by discharge of fuel.

(4) It can be used as radiation absorbers, heat stabilizers, light stabilizers, and smoke-retardants.

(5) For the chemical properties, ferrocene is similar to aromatic compounds which is not prone to have addition reaction but prone to have electrophilic substitution reaction. It can also participate in metallization, acylation, alkylation, sulfonation, formylation and ligand exchange reaction, which can be used for production of derivative with a wide range of applications.
