Abstract:
Process for controlling fungi in which plants that are to be protected are treated with a fungitoxic amount of a compound having the formula IN WHICH R1 denotes a member selected from the group consisting of tridecyl and cycloalkyl with from six to 12 carbon atoms as ring members and in which R2, R3, R4 and R5 denote a member selected from the group consisting of methylene and substituted methylene with at least one of the groups R2, R3, R4 and R5 being a substituted methylene group in which the substituents are members selected from the group consisting of methyl and ethyl, the said substituents occurring once or twice in each substituted methylene group.
Abstract:

[Also in Division D2] Water-soluble polyalkylenimine derivatives are prepared by reaction of polyalkylenimines with bifunctional alkylating agents wherein a polyalkylenimine which in the form of a 1% by weight aqueous solution has a viscosity of 1À03 to 1À6 centistokes at 25‹ C. is reacted with 0À5 to 25% by weight of epichlorohydrin (or the equivalent molar amount of another bifunctional alkylating agent having 2 to 4 carbon atoms in the molecule) at from 20‹ to 150‹ C. to such an extent that the reaction product, in the form of a 1% by weight aqueous solution, has a viscosity of 1À6 to 20 centistokes at 25‹ C. Examples of suitable bifunctional alkylating agents are epichlorohydrin, ethylene chloride, 1,3-dichloropropane, 1,4-dichlorobutane, dichlorohydrin and 1,2-3,4-diepoxybutane. Polyethylenimine is particularly suitable as the polyalkylenimine; other suitable examples being copolymers of 40 to 80% by weight of ethylenimine and 20 to 60% by weight of 1,2-propylenimine. The resulting polyalkylenimine derivatives are useful as assistants in the paper industry.
Abstract:
The continuous production of ethylene-imine comprises mixing an aqueous alkaline solution of NH2CH2CH2OSO2OH (the alkali being in at least stoichiometric amount) with an amount of high-pressure steam to produce a temperature of 150 DEG to 300 DEG C., passing the mixture through a flow tube, and cooling to below 120 DEG C. by pressure release.
