摘要:
The present invention relates to branched saturated hydrocarbons which are covalently modified with haloalkylene units. Said modified hydrocarbons show low values of wear and friction with respect to the corresponding non modified hydrocarbons and can be conveniently used as lubricants in applications wherein higher resistance to wear and friction is required.

The present invention related to a process for the manufacture of hydrogen-based lubricants modified with per(halo)fluorinated aromatic compounds, to the modified lubricants thereby obtained and to the use of the modified lubricants for the preparation of lubricant compositions.
摘要:
A method for imparting anti-seize protection and lubricant to threaded connections of protection during make-up and break-out is disclosed which includes adhering a metallic anti-seize film to threads of threaded connections and coating the film protected threads with a lubricating composition to form an anti-seize/lubricating system with reduced adverse environmental impact. The method can also include depositing a bonding film or layer onto the threads prior to adhering the anti-seize film.

摘要:
A coating and bonding composition is disclosed. The composition includes suspending, bonding and thinning agents, and a metallic flake. The composition may be used with an environmentally friendly lubricating composition to form an environmentally friendly lubricating system for protecting threaded connections from galling or other damage. That system may be used in a method for protecting threaded connections that includes the steps of: coating me threads, prior to make-up, with the coating and bonding composition and then coating them with the environmentally friendly lubricating composition, after the coated threads have dried.
摘要:
Disclosed is a lubricating oil composition containing a fluoroalkyl group-containing alcohol represented by the general formula:R.sub.f --R.sup.1 --OH (I)(wherein R.sup.1 is an alkylene group having 2 to 15 carbon atoms, and R.sub.f is a fluoroalkyl group having 5 to 16 carbon atoms, providing that the number of fluorine atoms in R.sub.f is at least 2n-3 (wherein n is the number of carbon atoms in R.sub.f), and each carbon atom in R.sub.f is bonded to at least one fluorine atom) and a polyether compound. This composition has excellent anti-seizure property and excellent high-temperature solubility in a refrigerant.
摘要:
An electrorheological fluid e.g. for selectively coupling clutch members consists of silicone oil containing 30 volume % of dispersed polyaniline. The polyaniline is acidically oxidised aniline subsequently treated with base.
摘要:
A method for producing a highly aromatic base oil of the present invention includes a step of hydrorefining a clarified oil to obtain a highly aromatic base oil having an aromatic content of 50% by mass or more determined by a column chromatography analysis method. The step of hydrorefining a clarified oil is preferably performed under conditions of a hydrogen pressure of 5.0 to 20.0 MPa, a temperature of 280 to 400° C., a hydrogen oil ratio of 300 to 750 NL/L, and a space velocity of 0.3 to 2.0 h−1. According to the present invention, a highly aromatic base oil used for rubber processing, asphalt reclamation and the like, and a novel method for producing a highly aromatic base oil can be provided.
