Reactivity Profile
DI-N-HEXYL PHTHALATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. DI-N-HEXYL PHTHALATE can react with oxidizing materials and strong alkaline materials.
Health Hazard
SYMPTOMS: Symptoms of exposure to DI-N-HEXYL PHTHALATE may include eye irritation, skin irritation or drying progressing to dermatitis, nausea, vomiting and dizziness.
Fire Hazard
DI-N-HEXYL PHTHALATE is combustible.
Safety Profile
Very mddly toxic by
ingestion and skin contact. Experimental
reproductive effects. A skin and eye irritant.
Combustible when exposed to heat or
flame; can react with oxidming materials. To
fight fue, use foam, CO2, dry chemical. See
also PHTHALIC ACID and ESTERS.
Check Digit Verification of cas no
The CAS Registry Mumber 84-75-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 84-75:
(4*8)+(3*4)+(2*7)+(1*5)=63
63 % 10 = 3
So 84-75-3 is a valid CAS Registry Number.

Synthesis and characterization of butylamine-functionalized Cr(III)–MOF–SO3H: Synergistic effect of the hydrophobic moiety on Cr(III)–MOF–SO3H in esterification reactions
Alavijeh, Masoumeh Karimi,Amini, Mostafa M.
, (2019/09/30)
Mesoporous solid acid catalysts with partially hydrophobic moieties, [Cr3O(BDC–SO3H)3?x(BDC–SO3NH3Bu)x]n, were prepared from [Cr3O(BDC–SO3H)3]n (MIL-101(Cr)–SO3H) and BuNH2 for the first time and then characterized by the Brunauer–Emmet–Teller (BET) technique, powder X-ray diffraction, field emission electron microscopy, Fourier transform infrared spectroscopy, and thermal and elemental analyses. The nitrogen adsorption–desorption study showed that the specific surface area and total pore volume of MIL-101(Cr)–SO3H decreased after the reaction with butylamine and formation of [Cr3O(BDC–SO3H)3?x(BDC–SO3NH3Bu)x]n. The prepared materials were used as catalysts to investigate the impact of hydrophobic moieties in esterification yields of phthalic anhydride with several alcohols as a probe reaction. The presence of butylamine as a hydrophobic group on MIL-101(Cr)–SO3H increases the esterification yield significantly for hydrophilic alcohols under solvent-free conditions. Moreover, results showed that [Cr3O(BDC–SO3H)3?x(BDC–SO3NH3Bu)x]n can be recovered and reused for several consecutive reactions without significant loss in catalyst activity.

Medium pore molecular sieves, SAPO-11, SAPO-31 and SAPO-41, have been synthesized using di-n-propylamine and diethylamine as the organic template. They have been characterized by various methods such as elemental analysis, X-ray powder diffraction, solid state MAS NMR spectroscopy, and FT-IR spectroscopy in the framework and hydroxyl regions. Catalytic activities of these materials in the esterification of phthalic anhydride with different alcohols have been studied. The catalytic activity of these material is in the order: SAPO-41> SAPO-11> SAPO-31.
