Embodiment 1

[0088] Example 1: 3,4-dihydro-4,4-dibenzyl-2-(3-sulfopropyl)isoquinoline Preparation of inner salt

[0089]

[0090] step 1. α, the preparation of α-dibenzyl-phenylacetonitrile (2): add benzyl cyanide (( 1), 5.0 g, 0.043 mol) and tetrahydrofuran (100 mL). Sodium hydride (60% in oil) (7.2 g, 0.1075 mol) was slowly added to the reaction over one hour. Once the addition was complete, the reaction was stirred at room temperature for 1 hour. Benzyl bromide (18.4 g; 0.043 mol) was added to the reaction and the reaction was stirred at 50°C for 18 hours. The reaction was evaporated to dryness, the residue was dissolved in toluene and washed with 1N HCl. use Na 2 SO 4 The organic phase was dried, filtered and evaporated to dryness to yield α,α-dibenzyl-phenylacetonitrile (2), weight = 7.7 g (65%).

[0091]Step 2. Preparation of 18-amino-2,2-dibenzyl-2-phenylethane (3): α,α-dibenzyl-phenylacetonitrile ((2), 7.0 g; 0.0237 mol ) was dissolved in borane-THF complex (1.1 eq...

Embodiment 2

[0094] Example 2: 3,4-dihydro-4,4-dipentyl-2-(3-sulfopropyl)isoquinoline Preparation of inner salt

[0095] The desired product was prepared according to Example 1, substituting benzyl chloride in step 1 with pentane chloride.

Embodiment 3

[0096] Example 3: 3,4-dihydro-4,4-dihexyl-2-(3-sulfopropyl)isoquinoline Preparation of inner salt

[0097] The desired product was prepared according to Example 1, replacing the benzyl chloride in step 1 with chlorohexane.

Abstract

This invention relates to cleaning compositions comprising organic catalysts having enhanced enzyme compatibility and processes for making and using such cleaning compositions.

Description

field of invention [0001] The present invention relates to cleaning compositions comprising organic catalysts and methods of making and using such cleaning products. Background of the invention [0002] Oxidative bleaches such as hydrogen peroxide are commonly used to remove stains and soils from clothing and various surfaces. Unfortunately, the above reagents are closely related to temperature ratings. Thus, when the above reagents are used in a cooler solution, the bleaching effect of the solution is significantly reduced. [0003] In an effort to address the above performance problems, the industry has developed a class of materials known as "bleach activators". However, since the above-mentioned substances fail rapidly when the solution temperature is lower than 40°C, new organic catalysts have been developed, such as 3,4-dihydro-2-[2-(sulfooxy)decyl]isoquinoline inner salt. Often, while these popular artificial catalysts are effective in lower temperature water con...
