Methyl hydrogenated silicone oil, help needed
Thread Content
The methylhydrogen siloxane that I had hydrolyzed contained HCl and structural chlorine, and during the washing process, a sticky-like substance was formed. This substance was actually oil surrounding water, and it disappeared after a few hours of settling. Although this oil-containing acidic water could settle, it **affected subsequent processing. What caused this situation of oil surrounding water? Is there a solution?
This issue can be resolved during the hydrolysis process; you need a feed distributor with high uniformity, as it can help address various problems such as oil-in-water phases, high acidity levels, and chlorine content in the hydrolyzed products. Additionally, you will need to figure out on your own how to control factors such as hydrolysis temperature and acidity.
What kind of feed distributor is needed to break up water-in-oil emulsions?
I can only guide you up to this point. I have been involved in the research and development of patent technologies for a company, so regarding technical issues I can only provide guidance on that aspect; as for more complex technical matters, I’m not able to offer much help. I believe that as an engineering technician, this hint is sufficient to solve such problems.
Could we explore this in more depth?
The finished products using this type of distributor haven’t been developed yet, but you can conduct experiments on your own. Based on mechanical principles, it should be easy to create a distributor that allows one fluid to be distributed evenly within another fluid! !
Bro 999, please leave me your contact info. I’m begging you!
What category does the fire hazard of methylhydrogen siloxane belong to?
This post was last edited by rjs999 on 2013-4-10 09:01. The open flash point of methylhydrogen siloxane is above 300 degrees, classifying it as a non-flammable liquid; however, at high temperatures (above 400 degrees for an extended period), its bonds break and hydrogen gas is released, making it flammable and classified as Category B. Generally, flammable and hazardous materials are not taken into consideration.
Tetramethyldisiloxane (hydrogenated dual-sealed version) has a flash point of -26 degrees and a boiling point of 71 degrees; it must be transported as a hazardous material.
Some information I found online states that the flash point of hydrogenated silicone oil in urgent delivery versions is around 130 degrees, so we consider it to belong to Category B. The flash points determined by the open cup method and the closed cup method are different, but the Building Code specifies the use of the closed cup method for measurement.
