Working with metal alkyls safely and effectively
Metal alkyls are compounds with direct metal–carbon bonds (Al–C, Zn–C). Their defining trait is high reactivity: they are powerful alkylating, reducing and co-catalytic agents — and, for aluminum/zinc alkyls, pyrophoric (ignite spontaneously in air). That same reactivity is what makes them indispensable in polyolefin catalysis and advanced materials.
Core grades and their roles
| Product | CAS | Primary use |
|---|---|---|
| TEAL (triethylaluminum) | 97-93-8 | Ziegler–Natta / metallocene co-catalyst; olefin polymerisation; reducing agent |
| TIBAL (triisobutylaluminum) | 100-99-2 | Co-catalyst & chain-transfer / scavenger in polyolefin plants |
| DIBAL-H (diisobutylaluminum hydride) | 1191-15-7 | Selective reducing agent in fine-chemical & API synthesis |
| DEZ (diethylzinc) | 557-20-0 | CVD / ALD precursor; polymerisation activator |
| TMA (trimethylaluminum) | 75-24-1 | MOCVD/ALD precursor (Al₂O₃ films); co-catalyst |
Where metal alkyls earn their place
Polyolefin catalysis
In Ziegler–Natta and metallocene processes, TEAL/TIBAL activate the transition-metal site and scavenge poisons (water, oxygen) from the monomer stream. Dosing, dilution and residency time directly govern molecular weight and morphology.
Semiconductor & advanced coatings
TMA and DEZ are delivered as ultra-high-purity precursors for atomic-layer deposition (Al₂O₃, ZnO) in logic, memory and optoelectronics. Purity ppb-level trace-metal control is essential.
Fine & specialty synthesis
DIBAL-H reduces esters to aldehydes at low temperature with remarkable selectivity — a staple in API and flavour/fragrance routes — while alkylaluminum reagents build C–C bonds in complex molecules.
Field example — steadier reactor activity
A PP producer saw catalyst productivity swing with seasonal humidity. By moving to a conditioned TEAL feed with inline moisture scavenging and a fixed TEAL: catalyst ratio, they flattened the activity curve and cut off-spec resin. The change was operational discipline around the alkyl, not a new catalyst. (Illustrative composite; specifics under NDA.)
Frequently asked questions
Why are metal alkyls handled under inert gas?
Aluminum and zinc alkyls are pyrophoric — they ignite on contact with air and react violently with water. They are transferred and stored under dry nitrogen/argon in sealed, often double-contained, systems.
What purity do semiconductor grades require?
Electronic-grade precursors are specified at ppb trace-metal and ultra-low moisture/oxygen levels, with dedicated cleanroom packaging to protect device yields.
Can metal alkyls be shipped internationally?
Yes, under strict dangerous-goods regulations (e.g., IMDG/ADR/IATA Class 4.2 & 4.3). We supply compliant packaging, documentation and, where needed, conditioned containers.
How do I choose TEAL vs TIBAL?
Both activate Ziegler–Natta systems; the choice hinges on chain-transfer behaviour, solubility and the scavenging demand of your monomer. Trial in a bench reactor is the reliable way to lock the ratio.
