Embodiment I

[0039] The purpose of this example was to prepare the overbased barium 1,3-diketonates / barium monocarboxylates of the present invention. This was achieved by replacing the nonylphenol of Comparative Example 1 with an equivalent amount of dibenzoylmethane. For this purpose, the following ingredients and their actual amounts were employed.

[0040] Element

[0041] The overbased barium diketonate / barium oleate / barium carbonate salt was prepared following the procedure of Comparative Example I, after substituting dibenzoylmethane for nonylphenol. Using approximately the same schedule as in Example 1 at approximately the same temperature for mixing the reaction ingredients, heating and charging the barium hydroxide and dibenzoylmethane, except that the carbonation step is carried out at approximately 310°F for approximately 3.5 Hour. About 21 ml of water was recovered to prepare a storage-stable liquid of the overbased barium salt. The storage-stable liquid was titra...

Embodiment II

[0043] In this example, octanoylbenzoylmethane was used instead of nonylphenol in Comparative Example I, and the following ingredients were used.

[0044] Element

[0045] Octanoylbenzoylmethane

[0046] The liquid overbased barium salts of diketonates / oleates / carbonates were prepared by following the procedure of Comparative Example 1, charging the reaction components into their reaction vessels, and subjecting them to similar reaction times and temperatures, except for the carbonic acid The heating is carried out at about 253°F for about 3 hours. During the course of the reaction, about 18.5 ml of water were removed to form the resulting storage-stable liquid, which was filtered to a honey color and titrated to 29.39% barium.

Embodiment IV

[0048] In this example, stearoylbenzoylmethane was used instead of nonylphenol of Comparative Example I, and the following ingredients were employed.

[0049] Element

[0050] Following the same procedure as Comparative Example 1, after carbonation at about 260°F for about 3 hours, about 16.5 ml of water was removed to prepare a liquid barium diketonate / barium oleate / barium carbonate, titrated to 23.22% barium.

Abstract

Liquid overbased alkali or alkaline earth metal carboxylates, particularly barium carboxylates, are prepared by a process which includes the use of a beta-diketone as a reaction promoter during carbonation. Mixed metal stabilizers containing the overbased metal carboxylates are used as stabilizers for halogen-containing polymers such as polyvinyl chloride (PVC).

Description

technical field [0001] The present invention relates to a process for the production of liquid overbased alkali metal or alkaline earth metal carboxylates, in particular barium carboxylates. Mixed metal stabilizers containing said overbased metal carboxylates are useful as stabilizers for halogen-containing polymers such as polyvinyl chloride (PVC). Background technique [0002] 使用烷基苯酚制备羧酸的高碱性钙盐或钡盐公开于以下美国专利号2,616,904;2,760,970;2,767,164;2,798,852;2,802,816;3,027,325;3,031,284;3,342,733;3,533,975;3,773,664;3,779,992;4,665,117;5,830,935;和5,859,267 . The use of these overbased metal salts in halogen-containing polymers is also described in the aforementioned patents. Additionally, these prior art patents also discuss the use of alkylphenols as accelerators in the manufacture of overbased metal salts. [0003] Alkali metal or alkaline earth metal salts are prepared, for example, when alkylphenols are used as accelerators for the reaction according to the teachings of US Pat. ...
