PHTHALATE SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
ftalat
Ftalatlar ya da ftalat esterler, ftalik asidin esterleri olup, çoğunlukla plastikleştiriciler olarak kullanılırlar. Ftalatlar, ftalik anhidridin metanol ve etanol ile tridesil alkole kadar alkol ile reaksiyona sokulmasıyla ya düz bir zincir halinde ya da bazı dallarla üretilerek üretilmektedir. Alkol zincirindeki karbon atomlarının sayısına bağlı olarak, çok farklı uygulamalar, toksikolojik özellikler ve sınıflandırma olmak üzere iki ayrı gruba ayrılırlar. Temel olarak polivinil klorürü yumuşatmak için kullanılırlar. Düşük molekül ağırlıklı ftalatlar, sağlık sorunları nedeniyle Amerika Birleşik Devletleri, Kanada ve Avrupa Birliği'ndeki pek çok üründe kademeli olarak değiştirilmektedir. Bunların yerine, yüksek molekül ağırlıklı ftalatlar verilir. 2010 yılında piyasada hala yüksek ftalat plastikleştiriciler hakimdi; Bununla birlikte, yasal hükümler ve artan çevresel farkındalık ve algılamalar nedeniyle üreticiler giderek ftalat içermeyen plastikleştiriciler kullanmaya zorlanmaktadır.
