Iodocarb or 3-iodo-2-propynylbutylcarbamate is a chemical compound from the group of carbamates . It is used as a fungicide and wood preservative against brown rot , white rot and blue stain . Iodocarb is not used in crop protection, but it is one of the most common active ingredients in wood protection.
Iodocarb is also used as a fungicide in cosmetics and cooling lubricants .
Extraction and presentation
Iodocarb is traditionally obtained by adding propargyl alcohol to n -butyl isocyanate and then iodination. Instead, 1-iodobutane and potassium cyanate can be reacted with one another to form n-butyl isocyanate in a one-pot reaction and then, after reaction with propargyl alcohol, they can be electrochemically iodized with the iodide released in the first step with the addition of sodium hypochlorite . This saves you having to deal with the dangerous n-butyl isocyanate.
