Example Embodiment

[0066] Example 1-4

[0067] The addition products of 1:1, 1:2, 1:3, 1:4 of diethylenetriamine (DETA) and n-butyl glycidyl ether (BGE) were prepared by reacting pure DETA with appropriate equivalent number of BGE. . DETA (40.00 g) was added to a three-necked flask equipped with an addition funnel, reflux condenser, thermocouple and magnetic stir bar. The amine is heated to 100°C under nitrogen. At this time, the heat source was turned off, and BGE was added to the amine at a rate that maintained the reaction temperature at 90-120°C. After adding 1 equivalent of BGE (50.92g), the reaction solution was heated to 100°C for 40 minutes, and then a sample was taken out (Example 1, 15.01g, 1:1 DETA / BGE adduct, light yellow oil). Subsequently, 2-4 equivalents of BGE were added to the reaction mixture at 85-120°C. After adding each equivalent, the reaction solution was heated to 100°C for at least 20 minutes, and the following samples were successively taken out of the...

Example Embodiment

[0068] Example 5

[0069] The 1:5 addition product of diethylenetriamine (DETA) and n-butyl glycidyl ether (BGE) was prepared by reacting pure amine with 5 equivalents of BGE. DETA (53.89g) was added to a three-necked flask equipped with addition funnel, reflux condenser, thermocouple and magnetic stir bar. DETA is heated to 80°C under nitrogen. At this moment, turn off the heat source, and add BGE to DETA at a rate that maintains the reaction temperature at 80-115°C. After adding BGE (342.53g), the reaction was heated to 100-102°C for 40 minutes to obtain a pale yellow oil (394.1g, 1:5 DETA / BGE adduct). This sample was used without further purification.

Example Embodiment

[0070] Example 6-10

[0071] Using the steps similar to Examples 1-5, 1:1, 1:2, 1:3, 1:4 and 1:5 diethylenetriamine (DETA) were prepared by reacting pure DETA with an appropriate number of EHGE. And 2-ethylhexyl glycidyl ether (EHGE) adduct. The obtained adducts are Example 6 (100g, 1:1 DETA / EHGE, dark yellow syrup), Example 7 (100g, 1:2 DETA / EHGE, very light yellow oil), Example 8 (100g , 1:3DETA / EHGE, very light yellow oil), Example 9 (100g, 1:4DETA / EHGE, very light yellow oil) and Example 10 (100g, 1:5DETA / EHGE, very light Yellow oil). These materials were used without further purification.

Abstract

A method for controlling the foaming of an aqueous organic compound-containing composition by the incorporation of a foam controlling amount of a compound of the formula: (1), where n and m are 2 or 3, x is 1-6, R=H or (2), and R' is a C4 to C22 alkyl group, where R' is a C4 to C22 alkyl group, the compound generating an initial foam height at least 30% less than a 0.1 wt% aqueous solution of dioctyl sodium sulfosuccinate (DOSS) when added at 0.1 wt% to the DOSS solution.

Description

technical field [0001] The present invention relates to the use of reaction products of polyamines and alkyl glycidyl ethers as foam control agents. Background technique [0002] In many wet applications and industrial processes, foam control or elimination is critical for optimum performance in the application and high process efficiency. The importance of foam control and elimination is highly recognized in the field, such as: water-based coatings, inks, adhesives, and agricultural formulation applications, and industrial processes such as oil well pumping, petroleum gas scrubbing, purification, disinfection, food processing , pulp and paper processing, fermentation, metal processing, polymer and chemical synthesis, wastewater treatment and fabric dyeing and finishing. [0003] Foam control agents are widely used in polymer production and processing because foam can lead to reduced throughput, efficiency and plant problems. In particular, severe foami...
