methyl [1-(sulfanylmethyl)cyclopropyl]acetate - Introduction
Methyl 1-(mercap Methyl) cyclo propane acetate(1-MCP) is a chemical substance widely used in the field of fruit and vegetable preservation. It is a colorless gas, at room temperature and pressure is liquid form. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: colorless liquid
-Molecular formula: C4H6S
-Molecular weight: 98.16g/mol
-Density: 0.97g/cm³
-Boiling point: 32-34 ℃
-Melting point:-96.5 ℃
-Solubility: Insoluble in water, soluble in organic solvents such as ethanol and ethers.
Use:
1. Delay the ripening and aging of fruits and vegetables: 1-MCP can delay the ripening and aging process of fruits and vegetables by inhibiting the synthesis of ethylene in fruits and vegetables and accepting ethylene signals, and effectively prolong the shelf life.
2. Improve the quality of fruits and vegetables: 1-MCP can prevent the loss of color, texture softening and quality of fruits and vegetables during storage and transportation, and keep their freshness and taste.
Method:
The preparation of 1-MCP is mainly obtained by gas phase reaction, and the common preparation methods are:
1.2-methyl mercapto -2-methyl propanol is generated by the reaction of 2-bromo -2-methyl propanol and sodium sulfate.
2. 1-MCP is generated by the reaction of 2-methylmercapto-2-methylpropanol and sorbitol.
Safety Information:
1-MCP is a low toxicity chemical, but still need to pay attention to the following safety matters:
- 1-MCP is a flammable liquid and should be kept away from fire and high temperatures.
-Wear appropriate protective equipment, such as chemical protective gloves and glasses.
-Avoid inhaling 1-MCP vapor and operate in a well-ventilated area.
-If ingested or exposed to 1-MCP, rinse immediately with water and seek medical attention as soon as possible.
Please note that the above content is a general introduction, and the specific application and operation process need to follow the relevant safety operation specifications and guidelines.
