Citrate plasticizer

The invention discloses a citrate plasticizer and a preparation method thereof, and the preparation method of citrate comprises the following steps: firstly, citric acid and alcohol react to prepare citric acid triester, and then dianhydride acylation is carried out to prepare carboxyl-containing citric acid triester. After chlorination, the carboxyl-containing citric acid triester and the tris(2-ethoxyl) isocyanurate are subjected to esterification reaction to prepare triester citrate containing the isocyanurate. According to the present invention, the preparation method has characteristics of simple operation, wide raw material source and mild reaction condition, and meets the industrial production, the prepared triester citrate containing isocyanurate has a good plasticizing effect and excellent thermal stability, low-temperature flexibility, solvent extraction resistance, migration resistance and flame retardance, and can be widely applied to plastic rubber plasticizers.

CITRATE-BASED PLASTICIZER COMPOSITION AND RESIN COMPOSITION COMPRISING SAME

The present invention relates to a plasticizer composition, including a lower alkyl-based citrate and a higher alkyl-based citrate at the same time, as citrate, wherein the ratio of a hybrid type to a non-hybrid type and the ratio of the lower alkyl groups to the higher alkyl groups are controlled so that effects are achieved. When applying the plasticizer composition to a resin, stress resistance and mechanical properties can be maintained at an equal or higher level, the migration and volatile loss properties and the plasticization efficiency can be balanced, and the light resistance and heat resistance can be remarkably improved.

Lubricant compositions containing hydroxy carboxylic acid and hydroxy polycarboxylic acid esters

Disclosed herein is a composition comprising: (A) a lubricant or a hydrocarbon fuel;(B) at least one hydroxy carboxylic acid ester or hydroxy polycarboxylic acid ester having the generic formula defined herein; and(C) at least one phosphorus-containing additive.
