 In other preparations, neutralization and deodorization are done in the reactor before the product is discharged.
 PEI 1800E if required 7 , add the following catalyst addition step between steps A and B.
 Vacuum was continuously applied while the autoclave was cooled to about 50°C while 376 g of 25% sodium methoxide in methanol solution (1.74 moles, 10% catalyst loading based on PEI nitrogen functionality) was added. The methoxide solution was pumped into the autoclave under vacuum, then the set point temperature of the autoclave temperature controller was increased to 130°C. Use a device to monitor the power consumed by the stirrer. Monitor the power of the stirrer, as well as the temperature and pressure. As the methanol was removed from the autoclave, the stirrer power and temperature values were gradually increased and the viscosity of the mixture increased and stabilized within about 1 hour, indicating that most of the methanol had been remove...
 160 g of fabric were treated with composition A. The fabric is then left to dry and goes through an ironing process set on linen. After further washing cycles, it was then observed that fabrics treated in this way showed better dye fixing properties than fabrics that had not undergone the ironing process.
 The same results were obtained with compositions B-H.
