Recently, I made two brews of IPN using very cold temps and I got barely any yield. When I made it using warmer temps.....ice bath....but reagents around 40-50F, I got a much better yield with high potency/clarity. So 32F and colder might not be the ideal temp for certain alkyl nitrites.
The quality/freshness of the alcohol seems to matter a lot. My amyl alcohol came to me factory sealed in December 2021 and my brews are all weak with off odors and they don't preserve well now. There was a steady downhill climb in quality, as I used more and more of the alcohol, leaving a bigger and bigger air gap in the bottle. The alcohol I used for the IPN was new with an expiration date of 2025. This IPN is potent as hell, but the amyl is a dud and actually made me feel a little sick.
So....the quality/purity of the alcohol probably matters a lot.

2C,H,,OH + H,SO, + 2NaN0, = 2C,H,,NO, + Na,SO, + 2H,O and a
slight excess of sodium nitrite used. The acid was gradually mixes with the
alcohol, the mixture cooled and poured very slowly to the bottom of a solution
of the sodium nitrite in three parts of water, keeping the whole cooled to 10”
or 12”. The amyl nitrite formed floats on the aqueous layer and is washed with
alkaline carbonate solution and dried over fused potassium carbonate. If absolutely pure reagents are used, the amyl nitrite so formed requires no distillation and is almost perfectly pure. With less pure grades of alcohol, distillation
must be resorted to.
The above was written by chemists trying to figure out why there was so much variation in amyl nitrite. They say it's the purity of the alcohol that makes all the difference.

What's interesting about these chemist's findings, from 1914, is that they said the sodium nitrite/acid/alcohol method achieved a very high purity without requiring a distillation step PROVIDED the reagents used were high quality, especially the ALCOHOL. They also mentioned how some of the alkyl nitrites were more prone to degradation/impurities, which amplified some of the physiological effects(for the worse).
These chemists were on a mission to discover why in the previous 35 years, the commercial amyl nitrite had so much variation, that much of it could scarcely be called AN.
