Problems solved by technology

It is well known that after a period of operation, all process equipment near aqueous media used for transport, storage and pre-dosing of liquids is more or less wet and polluted by humidity. At the same time, the practical application of the compound of formula I is hindered, especially the need to improve the labor protection of the operator

Embodiment 1

[0016] a) Prepare liquid preparation A, as an active medium, the compound 3,3-dimethoxy-1-propene (3,3-dimethoxy-1-propene) with CAS No. 6044-68-4 and the stable compound of the present invention Compound 1,1,1-trimethoxy-methane (1,1,1-trimethoxy-methane) with agent CAS No. 149-73-5 is mixed, thus the resulting mixture contains 98mol% active substance and 2mol% stabilizer. Thus, 100 grams of Formulation A contained 2.1 grams of stabilizer.

[0017] b) The formulation was prepared in this way and subsequently tested to see if there was free acrolein formation during storage in humidity-contaminated equipment.

[0018] The test apparatus consisted of 1 inch pipe fitted with 2 pieces of DIN2982, the material was stainless steel AISI316, the inner diameter was 25.7mm and the pipe length was 220mm. After the tube was filled with 0.15ml of filtered seawater from the south port of the German Northern sea island of Helgoland, the tube was closed on both sides with 1-inch hexagonal ...

Embodiment 2

[0026] Prepare liquid preparation B, as active medium, compound 3,3-dimethoxy-1-propene with CAS number 6044-68-4 and compound 1 with stabilizer CAS number 149-73-5 of the present invention, 1,1-Trimethoxy-methane was mixed so that the resulting mixture contained 95 mol % active substance and 5 mol % stabilizer. Thus, 100 grams of Formulation B contained 5.2 grams of stabilizer.

[0027] This formulation was subjected to the same test procedure as described in Example 1, part b).

Embodiment 3

[0029] Prepare liquid preparation C, as active medium, compound 3,3-diethoxy-1-propene with CAS number 3054-95-3 and compound 1 with stabilizer CAS number 122-51-0 of the present invention, 1,1-triethoxy-methane (1,1,1-triethoxy-methane) was mixed so that the resulting mixture contained 98 mol% active substance and 2 mol% stabilizer. Thus, 100 grams of formulation C contained 2.3 grams of stabilizer.

[0030] This formulation was subjected to the same test procedure as described in Example 1, part b).

Abstract

Stabilized 3,3 dialkoxy-1-propene-preparation containing a compound of the formula I wherein R=C1-C6 hydrocarbon group and a compound of the formula II Z(-R1)X(-OR2)Y where Z=C (carbon) or Si (silicon); R1=H or C1-C3 carbon group; R2=C1-C3 carbon group; x=0 or 1, x+y=4.

Description

technical field [0001] The present invention relates to a stable preparation of 3,3-dialkoxy-1-propene (3,3dialkoxy-1-propene). Background technique [0002] 3,3-Dialkoxy-1-propene is used in many different applications to liberate water from various unwanted organics. For example, US-A-3,690,857 teaches that the growth of aquatic plants in aqueous media and channels is harmless by adding 3,3-dialkoxy-1-propene to the water Fish groups, this claim can be refuted. This method is used to control a wide range of organisms present in aqueous media and including aquatic plants, marine animals, algae, fungi, bacteria, and the like. Aqueous media in trenches, ponds, and water systems can create many problems. [0003] Furthermore, it is known from US-A-5,183,944 that it is possible to treat aqueous media with acrolein, especially in circulating systems, whereby acrolein acetal is brought into contact with an acid such as sulfuric acid, and by This produces gaseous acrolein, whi...
