Seeking expert advice on chlorinated paraffins
Thread Content
First, what is the difference between chlorinated paraffin and chlorinated wax? I really don’t understand. Second, after searching online for a long time, I found specifications such as 42#, 52#, 60#, and 70#. The carbon chain length for the first three is around 14–17, and they are in liquid form; whereas the carbon chain length for 70# is over 20, and it is in solid form. Here comes the question: are there any chlorinated paraffins with carbon chains of more than 20 atoms that are still in a liquid state? The engineer insists on finding this; it’s urgent
Chlorinated paraffin is the English name for chlorinated paraffins, referring specifically to chlorinated alkanes. The name “chlorinated wax” can be translated as chlorinated wax, but we shouldn’t use it as a product name. Paraffin is divided into liquid paraffin and solid paraffin; liquid paraffin is also known as Liquid Paraffin. Its carbon molecules range from C11 to C18, with a normal alkane content of around 70%, while the remainder consists of isomeric alkanes and aromatics. Solid paraffin is also known as Wax Paraffin or Paraffin Wax, with carbon molecules arranged in structures consisting of more than 20 atoms. Generally, liquid paraffin is used to produce chlorinated paraffin products of grade 52 and below, whereas to produce chlorinated paraffins of grade 60 and above, solid paraffin or a mixture of both is required. After deep chlorination, the softening point of paraffin increases significantly. At room temperature, C20 exists in a paste-like state and is relatively soft. Solid paraffin available on the market, being a mixture, has a higher softening point; for example, refined wax grade 52 has a softening point of 52 degrees Celsius. After deep chlorination, its softening point rises to between 90 and 105 degrees Celsius. Therefore, it is not feasible to obtain deeply chlorinated paraffin that remains liquid at room temperature.
