CN104962087A - Preparation method of diisononyl phthalate
(1) preparation of diisononyl phthalate: 0.6t phthalic anhydride is proceeded to reactor, adds 1.8t isononyl alcohol, is warming up to 170 DEG C, start stirring, backflow 1h, adds 6Kg...
Diisononyl phthalate
Diisononyl phthalate ( DINP) is a phthalate used as a plasticizer. DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid, and is commonly used in a large variety of plastic items. Health Issues [ edit]
Diisononyl Phthalate: Chemistry, Environmental Path, and
These phthalate plasticizers are incorporated into the PVC polymer matrix to impart flexibility and workability in producing a wide range of consumer goods such as building materials,...
Fate of four phthalate plasticizers under various wastewater
The fate of four phthalate plasticizers during wastewater treatment processes at six different wastewater treatment plants (WWTPs) was investigated. Concentrations of benzyl butyl phthalate (BBP), di(2-ethylhexyl) phthalate (DEHP), diisononyl phthalate (DiNP), and diisodecyl phthalate (DiDP) were de
Diisononyl Phthalate - an overview | ScienceDirect Topics
Phthalate esters are prepared by the esterification of phthalic anhydride with two molar equivalents of an alcohol or an alcohol blend. Although almost any alcohol can be used to make a phthalate ester, it is usually only the esters of the C6 to C13 alcohols that are useful as PVC plasticizers.
- What is diisononyl phthalate?
- Diisononyl Phthalate is a liquid chemical compound with the molecular formula C26H42O4, commonly used in the category of phthalates. You might find these chapters and articles relevant to this topic. Plastisol formulation (a new method of stabilization).
- How are phthalate esters made?
- Phthalate esters are prepared by the esterification of phthalic anhydride with two molar equivalents of an alcohol or an alcohol blend. Although almost any alcohol can be used to make a phthalate ester, it is usually only the esters of the C6 to C13 alcohols that are useful as PVC plasticizers.
- Should phthalate esters be restructured?
- A radical restructuring is expected. Phthalate esters are a main group of plasticizers, including di- (2-ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DINP) as the most widely used phthalates, which can be the subject of argument regarding their probable side effects on children’s health.
- Are phthalate esters compatible with PVC?
- Esters made with C4 or C5 alcohols produce plasticizers with high-volatile losses, while phthalate esters made from alcohols with carbon numbers greater than C13 are not compatible with PVC. Performance of the plasticizer can vary greatly with changes in carbon number.
- How many PHR is a plasticizer?
- Plasticizer usage varies over a broad range by the properties desired for the product from a low of 15 phr to a high of 500 phr. Generally, 60–100 phr is used. Junmin Ji, ...
- What is a chemical name for phthalate?
- Representative Chemicals: Di- (2-ethylhexyl) phthalate (DEHP); Diisononyl phthalate (DINP); Diethyl phthalate (DEP); Di-N -butylphthalate; Dimethylphthalate; Methyl-glycol phthalate; Phthalic acid; Bis (2-methoxyethyl) ester.
