Biolubricants for refrigeration systems and other applications
The development of biolubricants from vegetable oils, more specifically refers to capric, caprylic, lauric, myristic, palmitic, stearic, oleic, linoleic, linolenic, ricinoleic, isooleic, isostearic, undecylenic fatty acids whose applications are for compressors in refrigerators, freezers, air conditioners, industrial compressors and as lubricants for the automotive line is provided. Such products are used in refrigeration compressors, more specifically in refrigerators and air conditioners, industrial compressors and lubricants for the small and large automotive sector. Due to the use of 90% renewable raw materials, the products are biodegradable, non-toxic and safe to be handled. These products, after use as lubricants, can be discarded due to their biodegradability or recovered to be used in other less rigid applications, such as for the production of polyester resins, polyols for the production of polyurethanes, or production of plasticizers for PVC, paints and varnishes.
