摘要:
The present invention generally relates to a process for preparing alkoxylated alkylamines and/or alkyl ether amines. The process consists of two stages and utilizes a catalyst with a multiple-charge counterion. The alkoxylated alkylamines and alkoxylated alkyl ether amines prepared by the process possess the peaked ethoxylation distribution and contain less hazardous by-product.

摘要:
The invention relates to a method for producing oxalkylated amines or alcohols, whereby a reaction mixture containing an amine or an alcohol or a mixture of two or more amines and/or alcohols and an alkylene oxide or a mixture of two or more different alkylene oxides are made to react in one or several successive reaction steps. At least one of the steps of the reaction occurs in the presence of a basic catalyst and the reaction mixture in at least one of the reaction steps contains formic acid or a formic acid salt or a mixture of the two or more or the reaction mixture is mixed with formic acid or a formic acid salt or a mixture of the two or more when oxalkylation is finished. The alkoxylates obtained using the inventive method have little natural colour or odour.

Described are φ, φ'-[α,φ-alkanediylbis(alkylimino)]bis(alkanolpolyethoxylates) in which (i) the alkane group has in the range of 4 to 12 carbon atoms, (ii) the alkyl groups can be the same or different, and are primary alkyl groups which contains 6 to 24 carbon atoms each, (iii) each alkanol group contains, independently, in the range of from 2 to 6 carbon atoms, and (iv) the number of ethyleneoxy groups in each polyethoxylate group is in the range of 2 to 50. These compounds are effective adjuvants for use with pesticides, especially herbicides and plant growth regulants, such as glyphosate.
