    摘要： Process to prepare a spindle oil, light machine oil and a medium machine oil base oil grade by (a) performing a separate catalytic dewaxing on a spindle oil fraction, a light machine oil fraction and a medium machine oil fraction as obtained in a vacuum distillation of a bottoms fraction of a fuels hydrocracking process; (b) performing a separate hydrofinishing of the light and medium machine oil fractions obtained in step (a); (c) separating the low boiling compounds from the spindle oil, light machine oil and medium machine oil fractions as obtained in step (a) and (b) and obtaining the spindle oil, light machine oil and medium machine oil base oil grade; (e) wherein the vacuum distillation is performed by alternatingly performing the distillation in two modes wherein the first mode (d1) the bottoms fraction is separated into a gas oil fraction, a spindle oil fraction, a medium machine oil fraction and a first rest fraction boiling between said spindle oil and medium machine oil fraction and in the second mode (d2) the bottoms fraction is separated into a gas oil fraction, a spindle oil fraction, a light machine oil fraction and a second rest fraction boiling above the light machine oil fraction.

    摘要： A vapor film-rupturing agent is provided that is prepared from asphalt as a staring material, so as to have a fraction (x) (% by mass) of a saturated component and a fraction (y) (% by mass) of an asphaltene component based on the total fraction 100% by mass of the saturated component, the asphaltene component, an aromatic component, and a resin component obtained by any one of analysis methods described in the Japan Petroleum Institute Standard and Manuals Testing Method for Petroleum Products JPI-5S-70-10 and the British Standard Test Method IP-469 that satisfy one or more of the following conditions (1) to (3): condition (1): 1.2926×(x)/100−8.113×(y)/100+2.3384≤2.400, condition (2): (y)≥7.0, and condition (3): ((y)/(x))≥0.5. The vapor film-rupturing agent is capable of preparing a thermal treatment oil composition having a high vapor film-rupturing effect with a characteristic number of seconds in the cooling capability test according to JIS K2242 (2012) of 2.50 seconds or less.

    摘要： A lubricating oil for press working contains a base oil and a fat or oil-containing additive and a calcium-containing additive added to the base oil. The proportion of the fat or oil-containing additive with respect to the whole volume of the lubricating oil for press working is 10 to 30%. The proportion of the calcium-containing additive with respect to the whole volume of the lubricating oil for press working is 5 to 15%.
