[0300] In the following examples, the individual ingredients in the cleaning compositions are expressed as percentages by weight of the cleaning composition.

example 1

[0303] 1mol 2-butyl-2-ethyl-1,3-propanediol + 4mol propylene oxide / OH, aminated

[0304] a) 1mol 2-butyl-2-ethyl-1,3-propanediol + 4mol propylene oxide / OH

[0305]In a 2 l autoclave, 322.6 g of 2-butyl-2-ethyl-1,3-propanediol and 7.9 g of KOH (50% in water) were mixed and stirred at 120° C. for 2 h under vacuum (<10 mbar). The autoclave was purged with nitrogen and heated to 140°C. 467.8 g of propylene oxide were added in portions within 6 h. To complete the reaction, the mixture was post-reacted for an additional 5 h at 140°C. The reaction mixture was sparged with nitrogen, and volatile compounds were removed in vacuo at 80 °C. The catalyst potassium hydroxide was removed by adding 2.3 g of synthetic magnesium silicate (Macrosorb MP5plus, Ineos Silicas Ltd.), stirring at 100° C. for 2 h and filtering. A light yellow oil (772.0 g, hydroxyl value: 248.5 mgKOH / g) was obtained.

[0311] 1mol 2,2,4-trimethyl-1,3-propanediol + 4mol propylene oxide, aminated

[0312] a) 1mol2,2,4-trimethyl-1,3-propanediol+4mol propylene oxide

[0313] 327.3 g of molten 2,2,4-trimethyl-1,3-propanediol and 8.5 g of KOH (50% in water) were dehydrated for 2 h in a 2 l autoclave at 80° C. and <10 mbar. The autoclave was purged with nitrogen and heated to 140°C. 519.4 g of propylene oxide were added in portions within 6 h. To complete the reaction, the mixture was post-reacted for an additional 5 h at 140°C. The reaction mixture was sparged with nitrogen, and volatile compounds were removed in vacuo at 80 °C. The catalyst was removed by adding 2.5 g Macrosorb MP5plus, stirring at 100° C. for 2 h and filtering. A light yellow oil (825.0 g, hydroxyl value: 172.3 mgKOH / g) was obtained.

[0314] b) 1mol 2,2,4-trimethyl-1,3-propanediol + 4mol propylene oxide, aminated

[0315] In a 9 l autoclave, 700 g of the diol mixture obtained from example 2-a, 1000 mL THF and 1500 g...

Abstract

The present invention relates generally to cleaning compositions and, more specifically, to cleaning compositions containing a polyetheramine that is suitable for removal of stains from soiled materials.

Description

technical field [0001] The present invention relates generally to cleaning compositions, and more particularly to cleaning compositions comprising polyetheramines suitable for removing stains from soiled materials. Background technique [0002] Due to the growing popularity of easy-care fabrics made of synthetic fibers, increasing energy costs and growing ecological concerns among detergent users, the once-popular warm and hot water washes have now given way to washing in cold water (30°C). and below). Many commercially available laundry detergents are even declared suitable for washing fabrics at 15°C or even 9°C. To achieve satisfactory washing results at such low temperatures, ie comparable to those obtained with hot water washing, the demands on low temperature detergents are especially high. [0003] It is known to include certain additives in detergent compositions to enhance the detergency of conventional surfactants in order to improve the removal of greasy stains ...
