Abstract
Disclosed is a storage-stable condensation product prepared from 1-amino-2-propanol and formaldehyde in a molar ratio in the range from 1:2.0 to 1:3.1. The condensation product contains less than 10% by weight of water. Also, disclosed is the preparation of the condensation product and the use thereof for reducing the amount of hydrogen sulphide in liquids and gases.
Claims19
Process for preparing a condensation product, containing less than 10% by weight of water, comprising the successive steps:
- Step a) of reaction of 1-amino-2-propanol is reacted with formaldehyde in a molar ratio in the range from 1:2.5 to 1:3.1 and at a temperature in the range from 50° C. to 80° C. to form a product;
- Step b) of removal of water from the product obtained at the end of step a), under reduced pressure to form the condensation product.
