What purpose does the addition of a few drops of water serve in the procedure for the synthesis of polyurethane?
"Water reacts with the toluene diisocyanate to produce carbon dioxide gas bubbles that expand the polyurethane as it polymerizes. "
What is the manufacturing method of foam?
Most foam is made from polyurethane.They start by making polyurethane. To make it, you mix a polyol with a diisocyanate. There are many polyols. There are two important isocyanates, toluene diisocyanate and methylene diisocyanate. (Two other diisocyanates are used to make urethane paint.) The choice of polyol governs whether the foam is hard or soft, and how soft or hard it is.Next, you mix in a blowing agent. The first blowing agent was water, which forms CO2 in contact with diisocyanate. They don't like making insulating foam with water, because the foam doesn't insulate as well.

How do air freshener emissions affect the indoor environment?
Air freshener can impact indoor air quality by adding potentially hazardous pollutants to the air. The use of Air fresheners is associated with elevated levels of volatile organic compounds (VOCs), such as formaldehyde, acetaldehyde, benzene, toluene, ethyl benzene, and xylenes, in indoor air.

What is the pH of toluene?
What is the pH of toluene?
Is toluene evaporates from water?
Toluene is not miscible with water; toluene is released by slow evaporation.
Is toluene diisocyanate used in furniture harmful to human body?
The use of toluene diisocyanate (TDI) and related compounds in products may result in consumer and general population exposures, particularly in or around buildings, including homes and schools. TDIis well known dermal and inhalation sensitizers in the workplace and have been documented to cause asthma, lung damage, and in severe cases, fatal reactions. Even if uncured TDI products are being used by professionals, they could be used in locations, such as surfacing running tracks and gymnasium floors, where unintended exposure of bystanders, especially children, could be a concern. It is important to determine whether there are uncured TDI products being used in ways that could present potential exposure concerns.
What is the odour of toluene?
Toluene is an aromatic compound.
