Abstract:

The objective of the present invention is to provide a glycol-based cleaning agent for industrial use, which has excellent ability of removing various kinds of industrial dirt such as solder pastes, flux residues and various oils adhering to articles, while having no flash point and being recyclable (recyclable by distillation) at atmospheric pressure. The present invention relates to a recyclable azeotropic cleaning agent for industrial use, which is characterized by containing an azeotropic mixture that contains (A) a glycol-based solvent represented by general formula (1) R1-O-[-CH2-CH(X)-O]n-R2 (wherein each of R1 and R2 represents an alkyl group having 1-3 carbon atoms, n represents 2 or 3, and X represents a hydrogen atom or a methyl group) and having a boiling point of 160-230°C at atmospheric pressure, (B) water, and if necessary, (C) a tertiary amine having a boiling point of 160-230°C at atmospheric pressure. This recyclable azeotropic cleaning agent for industrial use is also characterized in that: the azeotropic mixture contains the component (A), the component (B) and the component (C) respectively in an amount of 5-35 wt%, in an amount of 65-95 wt% and in an amount of 0-30 wt%; and the azeotropic mixture has an azeotropic point of 90-100°C at atmospheric pressure.
