⚗️ Chemical & Physical Properties
2,5-Diaminotoluene is a white to light brown solid with a distinct odor. It is soluble in organic solvents, but has limited solubility in water.
The molar mass of 2,5-Diaminotoluene is approximately 121.16 g/mol, with a density of around 1.08 g/cm^3. In comparison, common food items such as sugar and salt have higher molar masses and densities.
The melting point of 2,5-Diaminotoluene ranges from 98-100°C, while the boiling point is around 391°C. These values are much higher than those of common food items, such as butter and chocolate.
2,5-Diaminotoluene is slightly soluble in water and has a relatively low viscosity. In contrast, common food items like milk and juice have higher solubility in water and lower viscosity.
🏭 Production & Procurement
2,5-Diaminotoluene is primarily produced through the nitration of 2,5-dinitrotoluene followed by hydrogenation. The nitration reaction involves the addition of nitric acid and sulfuric acid to 2,5-dinitrotoluene to form the intermediate 2,5-dinitro-4-methylbenzenediazonium ion, which is then reduced with hydrogen gas to yield 2,5-Diaminotoluene.
In order to procure 2,5-Diaminotoluene, individuals or organizations may choose to purchase it from chemical suppliers or manufacturers. The compound may be available in liquid form or as a solid powder, depending on the specific needs of the buyer. Once procured, 2,5-Diaminotoluene can be transported in suitable containers or drums, following appropriate safety regulations.
Transportation of 2,5-Diaminotoluene should be done in compliance with hazardous material regulations to ensure safety during transit. It is crucial to use proper labeling and packaging to prevent any leakages or spills during transportation. Additionally, suitable transportation methods, such as trucks or specialized carriers, should be used to deliver 2,5-Diaminotoluene to its intended destination.
⚠️ Safety Considerations
Safety considerations for 2,5-Diaminotoluene include its potential for causing skin and eye irritation upon contact. It may also be harmful if inhaled or ingested, leading to respiratory irritation, nausea, and vomiting. Additionally, exposure to this substance may result in allergic reactions in some individuals.
The hazard statements for 2,5-Diaminotoluene include “Causes skin irritation” and “Causes serious eye irritation.” It is also classified as harmful if swallowed or if inhaled, with potential effects including respiratory irritation and nausea.
Precautionary statements for 2,5-Diaminotoluene advise avoiding skin contact and eye contact, as well as wearing protective gloves and eye protection when handling the substance. It is recommended to work with 2,5-Diaminotoluene in a well-ventilated area to prevent inhalation exposure, and to seek medical attention immediately in case of accidental ingestion or exposure.
