Definition
ChEBI: A carbamate ester that is carbamic acid in which the nitrogen has been substituted by a butyl group and in which the hydrogen of the carboxy group is replaced by a 1-iodoprop-2-yn-3-yl group. A fungicide, it is used as a preservative and sapstain control c
emical in wood products and as a preservative in adhesives, paints, latex paper coating, plastic, water-based inks, metal working fluids, textiles, and numerous consumer products.
Uses
Fungicide; mildewcide; preservative in cosmetics, paints and coatings, metal working fluids; wood protection.
General Description
Off-white solid.
Reactivity Profile
3-IODO-2-PROPYNYL BUTYLCARBAMATE is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.
Application

Clinical Use
Iodopropynyl butylcarbamate (3-iodo-2-propynyl-butylcarbamate) is a highly effective fungicide as well as a bactericide. It was first used in the 1970s as a film fungicide for paint and then as a wood preservative, where final use concentration up to 4% was permitted. For paint and coatings usually no more than 0.5% iodopropynyl butylcarbamate is used. For metalworking fluids, adhesives, textiles, and paper, concentrations between 0.1%and 0.2% are common. The Cosmetic Ingredient Review Expert Panel concluded that iodopropynyl butylcarbamate is safe as a cosmetic ingredient in concentrations less than or equal to 0.1%and that it should not be used in products intended to be aerosolized. By 1996, iodopropynyl butylcarbamate was used in 122 formulations reported to the United States Food and Drug Administration. Iodopropynyl butylcarbamate is found in a wide variety of occupational and consumer products, including shampoos, lotions, powders, makeup, baby products, paints, coatings, metalworking fluids, household products, cooling water, building materials, and contact lenses. It is an irritant, although at low concentrations few problems have been reported.
Synthesis
1) 68kg of 3-propynyl-1-hydroxy-3-acrylate and 45kg of n-butylamine were accurately weighed in 150L of dimethoxydimethyl ether, mixed and transferred to three reactors. The reaction system was cooled to 0-5 °C and 16 kg of concentrated hydrochloric acid solution was slowly added dropwise. After the dropwise addition, the reaction temperature was raised to 120°C and maintained at this temperature for 12 hours. Upon completion of the reaction, the system was cooled to 5-10 °C, followed by the addition of 11 kg of sodium iodide. The reaction mixture was heated to 25-30°C and the reaction was continued for 24 hours. At the end of the reaction, the solvent was removed by distillation under reduced pressure and 800 mL of water was added to the residue and stirred for 30 minutes. The reaction mixture was filtered and the filter cake was dried to give a final 157 kg of iodopropynyl butylcarbamate. The yield was 91% as n-butylamine.
