    • The invention relates to a high penetration - minimum value 30 0.1 mm at 25 DEG C - and low viscosity - maximum value 10 m /s - paraffin wax. The invention also relates to a process for producing said paraffin wax by redistilling a mixture of slack waxes and de-oiling the resulting individual fractions I, II, III and IV (the residue) to obtain foot oil I, foot oil II, foot oil III and foot oil IV. According to the invention at least two of the resulting foot oils are mixed with one another and optionally with up to 65 w/w % of a foot oil resulting from non-redistilled slack waxes to obtain a final mixture containing at least 15 w/w % of foot oil IV (petrolatum oil), and this mixture is de-oiled in a manner known per se in an apparatus used for de-oiling of slack waxes with a solvent mixture comprising ketones and aromatics with a ketone content of not less than 29 % by volume, wherein dissolution and mixing are performed at temperatures not higher than 125 DEG C and crystallization is performed at a final cooling temperature not less than -17 DEG C.
    • 本发明涉及25℃下的高渗透 - 最小值30±0.1mm,低粘度 - 最大值10m 2 / s - 石蜡。 本发明还涉及一种通过重新蒸馏松散蜡的混合物并使得到的各个级分I,II,III和IV(残余物)脱油得到脚油I,脚油II,足油 III和脚油IV。 根据本发明,所得脚油中的至少两种彼此混合,并且任选地含有至多65w / w%的由未重蒸的松散蜡得到的足油,以获得含有至少15w / w %的脚油IV(凡士林油),并且该混合物以本身已知的方式在用于使松香蜡脱油的设备中用含有不少于酮含量的酮和芳族化合物的溶剂混合物脱油 29体积%,其中溶解和混合在不高于125℃的温度下进行,结晶在不低于-17℃的最终冷却温度下进行。
