Modified Alcohol / Hydrocarbon Degreasers
MODIFIED ALCOHOL / HYDROCARBON
Baron Blakeslee is offering the next generation of Airless Vacuum Vapor Degreasers for use with modified alcohol, and hydrocarbon solvents. Baron Blakeslee is the ONLY American manufacturer of vacuum degreasers designed for modified alcohol and hydrocarbon solvents. Our products are designed, built and supported in America. We have a full time service department as well as a multimillion dollar inventory of spare parts in stock to keep your new Baron Blakeslee equipment running.
Baron Blakeslee offer both standard (https://www.baronblakeslee.net/airless-vacuum-vapor-degreasers/standard-airless-vacuum-vapor-degreasers/) and custom (https://www.baronblakeslee.net/airless-vacuum-vapor-degreasers/custom-airless-vacuum-vapor-degreasers/) Airless Vacuum Vapor Degreasers for use with modified alcohol and hydrocarbon chemistries. A compliment of standard and custom material handling and conveyor systems are available.
Modified alcohol solvents are unique in that they can be effective in removing both polar and non-polar soils. This can be beneficial for applications where both petroleum based and water soluble metalworking fluids must be removed.
Similar to traditional halogenated solvents, modified alcohols have low surface tension and low viscosity which allows the removal of soluble contaminants from complex geometries like capillary spaces and blind holes.

MODIFIED ALCOHOL / HYDROCARBON
Modified alcohol solvents are typically compatible with all metals, and may be used with other materials too, although temperature compatibility should always be considered with plastics, elastomers and other soft goods, but this is true of any cleaning process.
Compared to legacy solvents like methylene chloride, perchloroethylene and trichloroethylene, modified alcohols are not Hazardous Air Pollutants (HAPs), and the waste stream is generally considered to be nonhazardous so long as no hazardous materials are introduced in the cleaning process. Modified alcohols are CFC free, non-halogenated, nonflammable, PFAS free, REACH compliant, and have relatively low VOC content. Some modified alcohol formulations are said to be biocompatible according to ISO 10993-5 which is a test method to evaluate in vitro cytotoxicity of medical devices.
Like halogenated solvents, modified alcohol solvents may be recycled via distillation, and the vacuum degreasing equipment in which they are used is capable of thorough concentration of waste leaving minimal solvent in the waste stream.
Modified alcohol solvents boil at higher temperatures than conventional halogenated vapor degreasing solvents. For instance, of the typical fluorinated trans-1,2-dichloroethylene vapor degreasing solvents on the market, the highest boiling point of these solvents is generally about 118℉. Commercially available modified alcohol solvents generally boil between 321℉ and 392℉. These relatively high process temperatures, often require the use of a corrosion inhibitor to prevent corrosion from occurring on sensitive part surfaces as they cool to room temperature, post cleaning. As parts cool, moisture in the air can condense on part surfaces and increase the possibility of corrosion, thus necessitating the use of a corrosion inhibitor. Baron Blakeslee’s Airless Vacuum Vapor Degreasers in which these unique solvents are used, are designed to accommodate the addition of corrosion inhibitors.
MODIFIED ALCOHOL / HYDROCARBON
Modified alcohols may potentially become acidic when used in applications where chlorinated or sulfonated metalworking fluids are being removed. Therefore, modified alcohol solvents are formulated with stabilizers to inhibit the acidification reaction. An acid acceptance test is a simple titration, must be performed regularly to monitor the health of the solvent. If the acid acceptance titration reveals that the modified alcohol solvent is drifting out of control, stabilizer must be added. The formulators of modified alcohol solvents are the source for both acid acceptance test kits and stabilizer.
Hydrocarbon solvents are similar to modified alcohols, but hydrocarbons tend to offer slightly milder solvency, and may be slightly more environmentally friendly depending on formulation and sourcing of raw materials. In general, there is minimal difference in the design and features of the cleaning equipment for use with either modified alcohol or hydrocarbon solvents.
