Product Name: High Quality N,N - Diethyl - m - toluidine
CAS Number: 91 - 67 - 8
Appearance: It is usually a clear to pale - yellow liquid. This physical state makes it convenient for handling in various industrial processes.
Boiling Point: The boiling point of N,N - Diethyl - m - toluidine is around 213 - 215 °C. This property is crucial as it determines the conditions under which the product can be distilled, purified, or used in high - temperature reactions.
Density: Its density is approximately 0.933 g/mL at 25 °C. Density is important for determining the volume - to - mass ratio, which is useful in accurate dosing during chemical reactions and formulations.
Solubility: It is soluble in common organic solvents such as ethanol, ether, and benzene. However, it has limited solubility in water. This solubility characteristic is significant when considering its compatibility with different substances in various applications.
N,N - Diethyl - m - toluidine has a wide range of applications. In the polymer industry, it is used as an accelerator in the curing process of unsaturated polyester resins. By accelerating the curing process, it helps to improve the production efficiency of fiberglass - reinforced plastic products, such as boat hulls, automotive parts, and construction materials. In the rubber industry, it can be used as a vulcanization accelerator, enhancing the cross - linking of rubber molecules and improving the mechanical properties of rubber products, like tires and rubber seals.
It also plays an important role in the dye and pigment industry. It can be used as an intermediate in the synthesis of certain dyes, contributing to the color development and stability of the final dye products. In addition, it has applications in the field of organic synthesis, serving as a key reagent in the preparation of various organic compounds through chemical reactions such as alkylation and condensation.
When using N,N - Diethyl - m - toluidine, it is essential to follow safety procedures. Always wear appropriate personal protective equipment (PPE), including safety goggles, gloves, and a lab coat. Ensure proper ventilation in the working area to avoid the accumulation of vapors.
For its use as an accelerator in unsaturated polyester resin curing, it should be added to the resin system in a controlled manner. Usually, the recommended dosage is within a certain range, which needs to be adjusted according to the specific requirements of the curing process, such as the desired curing time and the properties of the final product. When using it in organic synthesis, accurate measurement and strict control of reaction conditions, such as temperature, pressure, and reaction time, are necessary to ensure the efficiency and selectivity of the reaction.
Case 1: Fiberglass - Reinforced Plastic (FRP) Manufacturing
In a FRP manufacturing company, N,N - Diethyl - m - toluidine was used as an accelerator for an unsaturated polyester resin. The company was producing small - sized boat hulls. By adding the appropriate amount of N,N - Diethyl - m - toluidine to the resin, the curing time of the resin was significantly reduced from several hours to less than an hour. This not only improved the production efficiency but also enhanced the surface quality of the boat hulls, reducing the occurrence of defects such as air bubbles and uneven curing. As a result, the company was able to increase its production capacity and improve the overall quality of its products, leading to higher customer satisfaction and increased market competitiveness.
Case 2: Rubber Tire Production
A tire manufacturing plant incorporated N,N - Diethyl - m - toluidine as a vulcanization accelerator. By using this product, the cross - linking of the rubber molecules was more efficient, resulting in improved mechanical properties of the tires. The tires showed better wear resistance, higher tensile strength, and improved heat resistance. This led to longer tire lifespans and better performance under various driving conditions, which in turn increased the market demand for the plant's tires.
