Problems solved by technology

[0004] Polyols have good performance in improving the thermal stability of PVC, improving the initial coloring and inhibiting "zinc burning", but some of its own shortcomings also limit its wide use
Most polyols have a small molecular weight and are rich in hydroxyl groups, making them oleophobic, difficult to integrate with PVC resin, and uneven distribution, which makes it difficult to fully exert thermal stability. Considering its advantages and disadvantages and existing mature technologies , which can be modified by partial esterification

Embodiment 1

[0023] Example 1 Adopt the synthesis method of the present invention, prepare polymeric ester-based calcium according to the following steps and analyze the obtained polymeric ester-based calcium product, wherein, the synthetic adopted catalyst of polymeric ester-based calcium is SO 4 2- / Oxide-type solid superacid, specifically a kind of SO prepared by Chinese patent ZL 200610035325.9 (patent name: a preparation method of solid superacid) 4 2- / TiO 2 -SiO 2 Solid super acid.

[0024] 1. Synthesis of polymeric ester-based calcium: premix 212 Kg of adipic acid and 232 Kg of pentaerythritol and put them into the reaction kettle evenly. When the reaction temperature reaches 145°C, add 0.8 KgSO 4 2- / TiO 2 -SiO 2 Solid super acid, collect the water released from the reaction; as the reaction temperature rises slowly, keep the reaction temperature at 200°C, when the collected water released from the reaction is 38Kg, slowly add 49Kg of calcium oxide, keep the reaction for...

Embodiment 2

[0039] Example 2 Adopt synthetic method described in the present invention, prepare macromolecular ester-based calcium according to the following steps: 182Kg of adipic acid and 218 Kg of pentaerythritol are premixed and evenly put into reactor, when reaction temperature reaches 140 ℃, add 0.9 Kg catalyst, collect reaction released moisture; along with the temperature of reaction rising slowly, the reaction temperature was maintained at 198°C, and when the moisture discharged from the collected reaction was 30Kg, 28 Kg of calcium oxide was slowly added, and the feed was kept for 1.3 hours to obtain high Molecular ester calcium.

[0040] The catalyst used in this example is SO 4 2- / Oxide-type solid superacid, specifically a kind of SO prepared by Chinese patent ZL 200610035325.9 (patent name: a preparation method of solid superacid) 4 2- / SnO 2 -SiO 2 Solid super acid.

Embodiment 3

[0041] Example 3 Adopt synthetic method described in the present invention, prepare polymeric ester-based calcium according to the following steps: 201Kg of adipic acid and 228 Kg of pentaerythritol are premixed and evenly put into reactor, when reaction temperature reaches 150 DEG C, add 1.0 Kg catalyst, collect reaction Released moisture; as the reaction temperature rises slowly, the reaction temperature is maintained at 202°C, and when the collected and released moisture is 30Kg, slowly add 32 Kg of calcium hydroxide, keep the reaction for 1.4 hours, and discharge the material to obtain High molecular weight calcium ester.

[0042] The catalyst used in this example is SO 4 2- / Oxide-type solid superacid, specifically a kind of SO prepared by Chinese patent ZL 200610035325.9 (patent name: a preparation method of solid superacid) 4 2- / ZrO 2 -SiO 2 Solid super acid.

Abstract

The invention relates to high polymer ester calcium and a synthesis method thereof. According to the invention, the high polymer ester calcium is calcium salt of pentaerythritol adipate formed by carrying out esterification reaction on adipic acid and pentaerythritol, adding a solid superacid as a catalyst and adding calcium oxide or calcium hydroxide to neutralize. The high polymer ester calcium, provided by the invention, has excellent comprehensive performance, when the high polymer ester calcium is used for a PVC (Polyvinyl Chloride) stabilizing system, the initial whiteness of obtained products, Congo red times, system compatibility, stability and the like are very outstanding, and the preparation method is simple so as to achieve industrial productions, and the high polymer ester calcium can be used for preparing a PVC stabilizing agent.

Description

technical field [0001] The invention relates to a polymer ester-based calcium and a synthesis method thereof, belonging to the technical field of organic synthesis of compounds. Background technique [0002] PVC material has been widely used because of its wide range of uses, good processing performance, low manufacturing cost, corrosion resistance, insulation and other good characteristics.
