An additive for oils that is capable of imparting oils such as lubricant base oils with superior wear resistance properties or friction resistance properties, and a lubricant. An additive for oils that includes a compound represented by formula (I) is used. A and B each represents a single bond or hydrocarbylene or the like, X and Y each represents a sulfur atom or single bond, and W and Z each represents a hydrogen atom or &#x2014;NRRor the like, provided that W and Z are not both hydrogen atoms. Rand Reach represents a hydrogen atom, a hydrocarbyl or a hydrocarbylcarbonyl or the like, and n and m each represents an integer of 0 to 5. 

Additive for oils and lubricant comprising the same

The invention provides a process for the preparation of a carbonyl compound in high efficiency by oxidizing an alcohol. The process for the preparation of a carbonyl compound of the present invention includes a step of oxidizing an alcohol in the presence of a compound of the formula (I) or a derivative or a salt thereof, and an oxidant, wherein Rand Rindependently represent hydrogen, a halogen, a nitro or acidic group, or an alkyl or alkoxy group, each of which optionally has a substituent, or Rand Rcombine the two carbon atoms to which they are boned to form an aromatic ring.

Process for preparation of carbonyl compound and pro-oxidant for preparation of carbonyl compound

The present invention provides a lubricating oil comprising an alicyclic compound represented by a general formula (I): 

Lubricating oil

The present invention provides a process for producing an &#x3b1;,&#x3b1;-bis(hydroxymethyl)alkanal represented by Formula (II): (wherein R represents an alkyl group, a cycloalkyl group, or an aryl group) which comprises reacting an aldehyde represented by Formula (I):R&#x2014;CH&#x2014;CHO &#x2003;&#x2003;(I)(wherein R has the same meaning as defined above) with formaldehyde in the presence of a basic catalyst and a phase-transfer catalyst.
