In some embodiments, a compound has the formula (I) where: Rand Rare alkyl or, together with the carbon atom to which they are attached, cycloalkyl; R, Rand Rare H or alkyl (formula II); Ris alkyl or where: Rand Rare H, alkyl or, together with the carbon atom to which they are attached, cycloalkyl; Ris H or alkyl; X is alkylene or is absent; and p is 0, 1, 2 or 3; and m and n are 0, 1, 2 or 3 provided that m is 0 when Rand Rare H. The compound is suitable for use as a base stock which provides low volatility for a given viscosity profile. The compound may be used in a lubricant composition for an internal combustion engine.

The invention comprises electrically heated cylinders to be placed immersed in the bottom of a tank of water. The heated cylinder is electrically heated by an electric heating element mounted within the heating cylinder. The heated cylinder has means to support the cylinder with one end slightly higher than horizontal from the other end. The upper end of the heating cylinder has radially directed outlet hole means directing water from within the cylinder out of the cylinder back into the water in the tank in at least three different directions. The three different directions are in a path laterally outward from the longitudinal axis of the cylinder in at least approximately 90 degree intervals to one another. The upper end of the cylinder has closure means to cause water within the cylinder to be directed out radially directed outlet means. The lower end of the cylinder has water inlet means whereby water may travel into the water inlet means along the heating element to be heated and travel out the radially directed outlet hole means in at least three different directions, an electric cord is provided having circuit wires from the surface to the heating element to engergize the heating element. A thermostatic switch is mounted to the cord at a location spaced away from the heated cylinder and near the surface of the water in the tank and the switch is connected to one of the current wires in the cord to control the action of the heating element.
