A method for reducing the content of a saturated hydrocarbon in oils and/or fats. The method includes subjecting raw material oils and/or fats to a short path distillation treatment under a temperature condition of 50° C. or higher and 270° C. or lower. In the short path distillation treatment, a feed rate of the raw material oils and/or fats to a short path distillation apparatus may be 30.0 kg/h.Math.m.sup.2 or less per unit area of an evaporation surface of the short path distillation apparatus. The feed rate may be 5.00 kg/h.Math.m.sup.2 or more and 25.0 kg/h.Math.m.sup.2 or less per unit area of an evaporation surface of the short path distillation apparatus.

Present invention relates to a process for reducing the MOSH and/or MOAH content from vegetable lauric oil, comprising steps of: a) subjecting the vegetable lauric oil to a short-path evaporation, wherein the short-path evaporation is performed at a pressure of below 1 mbar, at an evaporator temperature in a range of from 150 to 200° C. and with a feed rate per unit area of evaporator surface of the shorth-path evaporation equipment in a range of from 10 to 50 kg/h.m.sup.2, b) Contacting the retentate vegetable lauric oil of step a) with an adsorbent, and c) Subjecting the bleached retentate vegetable lauric oil of step b) to a further refining step carried out in an oil refining equipment consisting of a stripping column with packing and not more than one oil collection tray or in a deodorizer, and obtaining a refined retentate vegetable lauric oil.

Methods are described for removing contaminants, including glycidyl fatty acid esters, 3-monochloropropane diol and toxins from edible oils by using short path stripping at reduced temperatures and pressures.

The invention relates to a method for purifying at least one reaction product of at least one diisocyanate, comprising at least the following steps: (A) providing a mixture A at least containing the at least one reaction product of the at least one diisocyanate and, if applicable, the at least one diisocyanate, (B) adding, if applicable more of, at lease one diisocyanate to mixture A from step (A) in order to obtain a mixture B, and (C) separating off the at least one diisocyanate from mixture B from step (B) by distillation in order to obtain the purified at least one reaction product of the at least one diisocyanate. Furthermore, the present invention comprises the reaction product of at least one diisocyanate which can be obtained by the method according to the invention and the use thereof for producing polyurethane foams, polyurethane hydrogels, polyurethane elastomers, varnishes and bonding adhesives.

A continuous-feed vacuum distillation system with an integrated pre-heater is proposed. It operates continuously on the material to be distilled and heats such material to near-distillation or distillation temperature before it enters the distillation column. This eliminates the current practice of heating the feed material only to much lower temperatures in a feed vessel before it enters the distillation system and thereby eliminates the loss of distillation efficiency inherent in the conventional practice. Various alternative features of the claimed integrated pre-heater are also claimed.

A continuous-feed vacuum distillation system with an integrated degasser is proposed. The degasser uses the same or a different vacuum system as the downstream distillation column and operates continuously on the material to be distilled before it enters the distillation column. This eliminates the current practices of degassing the feed material in bulk, with auxiliary equipment, before it enters the distillation apparatus, a difficult and time-consuming procedure, or using the distillation system in a low temperature state under vacuum, to remove the gas from the feed material, which is also inefficient. Various alternative features of the claimed integrated degasser are also claimed.
