  • Food grade compressor oil
    Patent number: 5578557
    Abstract: A food grade compressor oil for use in a high pressure compressor includes a base oil, an N-acyl derivative of the amino acid sarcosine, an imidazoline, and an amine-phosphate. Each of the three additives comprises no more than 0.5% by weight of the oil composition, and results in high lubricity and very low corrosion even when water is present in the oil. The compressor oil may also include polybutene which serves as a thickener, and an antioxidant. The compressor oil of this invention is particularly well suited for use in a hypercompressor used in the manufacture of polyethylene.

  • Water-based hydraulic fluid containing an alkyl dialkanolamide
    Patent number: 4342658
    Abstract: Hydraulic fluids or metalworking lubricants are prepared utilizing mixture of water and, as lubricants and corrosion inhibitors, an alkyl dialkanolamide, a polyoxyethylene ester, and an ethoxylated alkylaryl phosphate ester. The compositions have improved extreme pressure lubricating and wear preventing characteristics and are non-flammable. The compositions can be thickened if desired using a polyglycol-type thickener and can contain conventional corrosion inhibiting and extreme pressure lubricating additives known in the prior art. Stable concentrates comprising a phosphate ester, a polyoxyethylene ether, and an alkyl alkanolamide can be prepared.
